  ### 20. My experience with Informix

**Rating:** 3.0/5.0 stars

**Reviewed by:** Kenny Alexander B. | Small-Business (50 or fewer emp.)

**Reviewed Date:** July 17, 2018

**What do you like best about IBM Informix?**

Informix is a great engine. It's fairly straightforward to learn. I have taken 2 sysads and had them be effective at the end of a day of training. Always requires less headcount to support. As far as being able to take advantage of ALL system resources, Informix can do it. Have seen other db's hit limits, but not Informix. Also, the user community is very strong. Those who use Informix are usually very passionate about it and believe in it.

**What do you dislike about IBM Informix?**

Although I have not installed a version 12 and above, installation was a little odd from time to time. It's serious software so it needs to be done correctly but IBM could do a better job there. SQL support can also be a little more up to date. The big editions can be pricey and powerful servers, even if you do not need all this power.

**What problems is IBM Informix solving and how is that benefiting you?**

I have used it for mission-critical OLTP financial services and have found it very robust and stable.

Required minimum maintenance and uptime is great.

  ### 31. Always a pleasure 

**Rating:** 5.0/5.0 stars

**Reviewed by:** Spokey W. | Director, Information Technology and Services, Enterprise (> 1000 emp.)

**Reviewed Date:** April 25, 2017

**What do you like best about IBM Informix?**

I like the performance, the ease of use and maintenance and generally very talented and helpful support team. Setting it up is easy. Performance out of the box is great. Tuning it is very easy and the latest versions have outstanding diagnostics. It also has a remarkable feature set, especially if you look at the ease of a grid implementation compared to other vendors. And then there's the extensibility. 

**What do you dislike about IBM Informix?**

IBM does very little to market Informix. I can't blame them, they have thousands of software products, but it means the product has a lot less market awareness than it deserves. Security is a bit of a grey area, but it's no more of an issue than it is for any other vendor.

The documentation for TimeSeries is not up to par with the rest of the product set. The people designed and built the various DataBlades are some of the smartest people I know, sadly the documentation doesn't really get the rest of the world up to speed. I'd definitely recommend some consultancy if you're going to implement TimeSeries.

**Recommendations to others considering IBM Informix:**

Do it. IBM's marketing is terrible, but the product is superb: easy to install and configure, easy to administer and incredibly powerful and fast.

**What problems is IBM Informix solving and how is that benefiting you?**

Over the years, I've solved pretty much every kind of business problem, whether ERP, logistics, telco, retail, financial, medical... whatever, really. Lately I'm using Informix to help solve time series problems in the energy and utilities market.

Benefits include blistering performance, outstanding uptime, incredibly light-touch admin and integration with pretty much every development platform.

  ### 32. Informix Database

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Commercial Real Estate | Enterprise (> 1000 emp.)

**Reviewed Date:** January 19, 2018

**What do you like best about IBM Informix?**

The performance and the ease of using it. The setup was fairly easier then others.  Maintenance is minimal and so is downtown 

**What do you dislike about IBM Informix?**

lack of roadmap and lack of features . Not many software out there that uses Informix as db. 

**Recommendations to others considering IBM Informix:**

Just do it. Been working with Informix for about  years now. There is no indirect cost to use it which is great 


**What problems is IBM Informix solving and how is that benefiting you?**

reliability - Zero shutdown in last 2 years
Hardware - Current application is housing over 4000 users 
The NoSQL is a great plus
In house data analytics systems 

  ### 33. High volume OLTP database

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Gambling & Casinos | Enterprise (> 1000 emp.)

**Reviewed Date:** June 05, 2017

**What do you like best about IBM Informix?**

We get direct support from IBM experts and are closer to the development team as a large customer that we would be if we ran Oracle or SQL Server, for example. We manage high OLTP volumes running a site turning over in excess of £1bn+ annually and the product is scalable and by and large very reliable. We find the replication and high availability features and are very good and priced very competitively compared to other offerings.

**What do you dislike about IBM Informix?**

There could always be more features and a faster development roadmap. I am hoping that the new HCL partnership will go some way to address this.

**What problems is IBM Informix solving and how is that benefiting you?**

It provides us with a reliable high-availability ACID-compliant database product capable of scaling to both large transaction volumes with databases 10s of Tbs. Amongst other things it has facilitated the rapid growth of our business.

  ### 35. Extremely durable, powerful, reliable and fast db engine

**Rating:** 4.0/5.0 stars

**Reviewed by:** Peter M. | Database Systems Architect, Telecommunications, Enterprise (> 1000 emp.)

**Reviewed Date:** April 08, 2015

**What do you like best about IBM Informix?**

Informix is a great engine.  It's fairly straightforward to learn.  I have taken 2 sysads and had them be effective at the end of a day of training.  Always requires less headcount to support.  As far as being able to take advantage of ALL system resources, Informix can do it.  Have seen other db's hit limits, but not Informix.  Also, the user community is very strong.  Those who use Informix are usually very passionate about it and believe in it.  



**What do you dislike about IBM Informix?**

IBM seems to promote their db2 product line in all of their marketing.  There aren't as many third party tools or commercial off the shelf software out there written to use Informix as the underlying db, which can be very frustrating.  

**Recommendations to others considering IBM Informix:**

I consider Informix to be the Humvee of the database world.  It's extremely stable, powerful, and flexible.  IBM has recently changed it's licensing/cost model to be a little more like Oracle in that there are extra pieces you can buy to enhance the experience (enterprise replication being one).  The biggest knock against Informix is that no one outside of the existing user base seems to know it's still heavily used.  Look on any job board, and you'll see at least a 10:1 ratio of any other db to informix.  I've seen informix in use at numerous locations and the informix teams are always smaller and handling more activity.  I've used MSSQL, Oracle, MySQL, and db2.  I simply prefer Informix.

**What problems is IBM Informix solving and how is that benefiting you?**

Have only used it for OLTP type activity.  I can't speak to the warehousing aspect.  For OLTP it can provide continuous uptime for many different types of applications.  

  ### 36. Informix. The best database.  Period.

Informix offers six different types of data replication, distributed database, sharding, central master database, and other schemes for scaling and customizing the location and availability of your data.  It offers load balancing tied to disaster recovery/high availability and the ability to very quickly bring additional servers online to handle unusual load.  Data can be distributed and/or replicated across homogeneous or heterogeneous server farms.  Server version upgrades can be applied to a cluster of servers while permitting users to connect to the database and continuously access their data with no downtime.  Servers and client connections can be configured to guarantee that no transactions are lost, even if the primary server or its host goes offline.  This combination of features ensures that Informix is always on and always available.

Easy to install, very easy to use, powerful, versatile and easy to manage and configure

**What do you dislike about IBM Informix?**

It lacks built-in functions for hierarchycal recursive trees building, querying and traversal

**Recommendations to others considering IBM Informix:**

I believe this is one of the best commercial RDBMS. Version 12 supports SQL and NoSQL paradigms in the same database. It also has a very good interaction with the Java platform and if you are a user of the 4GL programming language or its competitors such as Querix Lycia, using either is way easy and straightforward.

One of the best tools I have ever used is onstat. This command is like talking to the database engine on a one to one basis.

**What problems is IBM Informix solving and how is that benefiting you?**

Very large information systems with a huge database. Data history of more than 10 years in a single database

  ### 38. Best customer loyalty rate in the "for charge" area

**Rating:** 5.0/5.0 stars

**Reviewed by:** Eric V. | Member of Board of Directors, Enterprise (> 1000 emp.)

**Reviewed Date:** April 10, 2015

**What do you like best about IBM Informix?**

* Reliability and stability: the identified record uptime is more than 6 years uptime
* Scalability: real multithread architecture allows smooth horizontal and vertical scalability
* Best rate for performance / hardware sizing: amazing performance level achieved with very moderate size hardware
* Best rate for staffing: no need for an army of DBA. Some companies handle 30,000+ informix servers with a team of 6 DBA's 24/7/365
* Replication  functionality is very complete, although very simple to admin
* the Informix Warehouse Accelerator is a software appliance that you plug into Informix, that can turn BI/DS queries by 700+ times faster, with no necessity to rewrite the DS applications not replug them anywhere else
* Works great on ARM/Quark processors, making it a great asset for IOT


**What do you dislike about IBM Informix?**

* Some of the SQL language is not yet as rich as other DBMS vendors
* IBM poorly promoting one of their best assets, although this is changing for better now



**Recommendations to others considering IBM Informix:**

Informix has poor visibility on the market. Make your own idea with user companies and you will see that a company that uses Informix does not want anything else, when speaking on technical terms.

Best way to achieve to register to the International Informix User Group http://www.iiug.org and or attend the Annual IIUG Conference www.iiug2015.org


**What problems is IBM Informix solving and how is that benefiting you?**

Speaking for customers in Health and Finance:
* reliabilty: server not shutdown since 20010
* staffing: 1/7 of a DBA for a 4000 users Informix system, 4 DBAs for smaller Oracle systems
* hardware: 4000 users working 
* hybrid possibilities: Informix is ready for NoSQL and works better than MongoDB. My customer will
develop new applications in MongoDB client, accessing Informix Database Server, and mix SQL data with NoSQL data.

  ### 39. Informix is unfairly the unknown best data manager

**Rating:** 5.0/5.0 stars

**Reviewed by:** Andrés R. | Principal Database Architect, Internet, Mid-Market (51-1000 emp.)

**Reviewed Date:** April 09, 2015

**What do you like best about IBM Informix?**

To explain what I like best, I am going to refer to two aspects: A) NoSQL vs RDBMS and B) Freeware and Licensed Engines

A) Distributed data is based on replication, and data partitioning lets you not only to scale your overall performance up, but also improve availability. There are two streams, one that is based on Hadoop and the other one is based on Sharding, the first one requires a huge amount of disk space, another invisible cost, and that initially none is caring about, as the storage costs drops, no need to worry or concern about data duplication and wasting space. In addition to the space issue, it is that the data is open, and there are not many security tools yet to hide the data and secure it. I am not sure everyone shares or knows these things…, so again this is confronting people with different ways of thinking. On the other hand maintaining replication in Hadoop is not a plug and play thing, it also has its challenges and requires complex java scripting. At last if we use Hadoop we are going towards a NoSQL or unstructured DB, and again, this is where many people get confused with…, so why turning the wheel to the opposite direction!, whilst we can use distributed data implemented in RDBMS (sharding)…, we have to have in count that NoSQL sacrifies consistency mainly by a very bad space consumer optimistic locking method to avoid dealing with atomicity and isolation.
Definitely NoSQL can’t replace RDBMS, as the BASE model is for some specific use cases, and for companies that defined their own solutions no other in the market was able to do…, but at that time!, RDBMS have now also powered up their engines, and in one case have even started to integrate and improve the unstructured model integrating it with the structured one, in the same data repository combining the best of both worlds, this is keeping up with the performance and capacity, without scarifying consistency, atomicity and isolation at the same time!.
There’s just one company that understood this problem and started working in a new paradigm, and this is to support the unstructured data model together with the structured one. This company is IBM, and its powerful INFORMIX engine. In any of the scenarios, either if by sharding or doing data partitioning required to scale out horizontally, a database engine has needs a very strong replication technology. 
INFORMIX deployment has been driven by its strengths in replication – Informix employs one of the industry’s most scalable and efficient replication architectures – and data management. It also combines strengths in embedded data management with low administrative overhead, highly effective use of server resources and enterprise-class resilience.

INFORMIX is oriented to solving the massive change that is occurring in computing environments around the world. Specifically, unstructured data is flooding into organizations and companies are struggling to choose between a relational or NoSQL database to handle it. While NoSQL offers the ability to have dynamic elasticity with data and its organization, these databases lack essential elements such as scalability, security, flexible deployment, transaction support and full data integration. INFORMIX offers a solution that can natively handle NoSQL and structured data simultaneously providing a single system with the seamless integration of all data within the enterprise. It is meant to help developers use native JSON and BSON data types as well as other NoSQL functions (including sharding) for complete plug-and-play compatibility with MongoDB and other NoSQL databases. Application developers can access structured and unstructured data in a single statement and join them together as needed. NoSQL applications can use the enterprise-level capabilities of a structured database system including transaction support, backup and recovery, H/A, compression, enhanced scalability, security and access control. All these last features are not minor and characteristic of any other NoSQL engine.
I think that the hybrid development capability of INFORMIX-NoSQL to manage and present both structured and structured data repositories, is going to be very important as organizations realize that 1) there is value in the new flexible schema paradigms like JSON, 2) existing apps can benefit from being able to present this data, 3) JSON based applications could benefit from access to the relational data that is already in the organization's relational databases, 4) NO new hires will be required to work in the NoSQL/JSON space, simplifying the complex, expensive, slow, and error prone daily ETL, from multiple data sources.

B) This is TCO (Total Cost Ownership). This is to do with how easy an engine is to be maintained, this is then to do with TBF (Time Between Failures) or unplanned downtime, and the much the technology allows you to avoid the downtime or plan downtime to reduce it. All this at the light of the incurring expenses to maintain it, support it vs licensing costs. 

I always like to call these as DIRECT and INDIRECT COSTS. 

DIRECT COSTS is very simple, it is represented by the licenses cost.
INDIRECT COSTS are the ones that NONE seems to sees, it is incredible!. This is why one platform needs more resources than others…, it is simple math, if a platform is all the time requiring an engineer to touch here, and there, today, next month again the same thing in the same place, in one word REDOING!. This is consuming most of te DBA time, that could be used to grow the business. If the DBA spends most of his time in recurrent fixes!..., then it is simple, another DBA is required. It is not just what we redo, but also what we can't do because we are stuck fixing. INDIRECT COSTS are invisible!, incredible, but real. 
There are also many aspects to consider as INDIRECT COSTS, such as performance, capacity, how much an engine can do with it…, and I am talking about using the same h/w, same data, but how much it is able to process is key…, so HOW MUCH THE ENGINE CAN DO WITH LESS!.

**What do you dislike about IBM Informix?**

The bad marketing there is around INFORMIX. I hate ppl when they talk about INFORMIX as an OLD technology.

**Recommendations to others considering IBM Informix:**

Run a ROI and TCO, benchmark it, you'll love it.

  ### 40. The fastest and more reliable database ever used for business application

**Rating:** 5.0/5.0 stars

**Reviewed by:** Francesco V. | Sales and Technical Support Specialist, Information Technology and Services, Mid-Market (51-1000 emp.)

**Reviewed Date:** July 06, 2015

**What do you like best about IBM Informix?**

Informix provides great features for every kind of use: do you need to setup an high-availability environment? grant simultaneous access to a broad mix of applications? manage terabytes of data? spread your production database on different nodes? use physical and virtual servers with different OSs? Just a very few examples about what you can achieve using Informix.

**What do you dislike about IBM Informix?**

The IBM price list uses the Processor Value Unit concept - aka "PVU", which is quite difficult to calculate and manage by the customers. Unfortunately for complex installations the PVU pricing also become very expansive.

**Recommendations to others considering IBM Informix:**

Consider the worldwide market of Informix: telco, healthcare, industries, public administrations, finance and many others. Each market segment can find with Informix a very good and agile friend, helping to minimize technical problems... and increase business. Also evaluate TCO for complex environments: Informix allows to save time in the administration and have a very strong support all around the world.

**What problems is IBM Informix solving and how is that benefiting you?**

Every application have peculiar features. This means that normally everytime you have to setup new applications to cover new business needs, you have to think about what development language has been used, what is the target platform, what is the way to connect the application to the backend/data, what level of integration do you need and of course how many users you need to keep concurrently online. All these questions can reflect an impact (or problems) on the database side. Using Informix you have "powerful weapons to fight new business needs" and lots of knowledge (articles, blogs, tech-notes) on how to implement exactly what you need. In my experience I did complex installations using Informix Connection Manager - aka "CM", which is the way to separate the application layer from the database layer and to give to the applications a list of rules about how to connect to the right server, the right database and get the best performance possible to the production environment. This always allows customers to implement very secure and fast architectures, and schedule servers management with no application block and data loss. With a few people in my team, I can manage hundreds of installations, avoiding to loose time to manage Informix instances, and having time to continuosly implement new solutions for new needs.

  ### 41. Simple to Install, Configure and Maintain

Ease of administration, built in replication for Business Continuity and for different schema for Data Warehousing. Ability to 'setup and forget'. Runs on any platform I choose: Unix (preferable), Linux or Windows.

**What do you dislike about IBM Informix?**

The last windows install I undertook was not easy, but that was 3 versions (of Informix) ago.

**What problems is IBM Informix solving and how is that benefiting you?**

Fundamentally the entire business runs on Informix. Sales Order placement and fulfilment, product warehousing (receipt and despatch). Purchase Order generation and all Ledgers.

  ### 42. I don't like databases, I love Informix

**Rating:** 4.5/5.0 stars

**Reviewed by:** Jean Georges P. | COO, VP North America, Information Technology and Services, Small-Business (50 or fewer emp.)

**Reviewed Date:** April 09, 2015

**What do you like best about IBM Informix?**

During most of my career, I was involved with software projects and products. I was managing developers and system administrators. The reason we picked Informix was clearly because of its legendary & proven reliability, which brought an awesome TCO to the projects. I like that it follows the business needs: extensibility, XML, NoSQL, and now IoT. It really makes sense for me. I like that there are a lot of editions so it fits your needs pretty well.

**What do you dislike about IBM Informix?**

Although I have not installed a version 12 and above, installation was a little odd from time to time. It's serious software so it needs to be done correctly but IBM could do a better job there. SQL support can also be a little more up to date. The big editions can be pricey and powerful servers, even if you do not need all this power. 

**Recommendations to others considering IBM Informix:**

The community is one of the biggest asset of Informix, discover the community on the IIUG web site at http://www.iiug.org and through its yearly conference.

**What problems is IBM Informix solving and how is that benefiting you?**

The benefits iInformix brought is mainly a great TCO. 

  ### 43. I have loved working with Informix, I think it has all the necessary features and very stable

**Rating:** 4.5/5.0 stars

**Reviewed by:** Omer Saeed K. | Sr MySQL DBA, Computer Networking, Mid-Market (51-1000 emp.)

**Reviewed Date:** April 10, 2015

**What do you like best about IBM Informix?**

High availability is great (HDR, RSS, Connection Manager)

**What do you dislike about IBM Informix?**

It doesn't support materialized views. And also SQL query language should be further enhanced to add functionality like "minus" operator and bit more sql enhancements that other databases do provide. 

**Recommendations to others considering IBM Informix:**

Informix has great potential to be one of the top databases in the market but I think, IBM is not putting much efforts in the marketing and development of Informix. 
But, still Informix can compete with any databases in the current market and its comparatively low cost of ownership could make it suitable for a lot of organizations as well.

**What problems is IBM Informix solving and how is that benefiting you?**

I have used it for mission-critical OLTP financial services and have found it very robust and stable.
Required minimum maintenance and uptime is great.
Provides multiple HA options/technologies

**Reviewed Date:** August 13, 2015

**What do you like best about IBM Informix?**

It just works, and have a lot of functionality

**What do you dislike about IBM Informix?**

IBM don't promote it as it should. This does Informix a less used database with decreasing number of professionals

**Recommendations to others considering IBM Informix:**

Consider to understand all the features that implement because you can save a lot of developing time. Excellent ROI among commercial databases.

**What problems is IBM Informix solving and how is that benefiting you?**

Business oriented software, web based

**Reviewed by:** John C. | Senior Informix/SQL Server Database Admin, Pharmaceuticals, Enterprise (> 1000 emp.)

**Reviewed Date:** April 17, 2015

**What do you like best about IBM Informix?**

With all of the turmoil that Informix has had to go thru it still shines as an amazing RDBMS that can handle any type of application that is thrown at it.  Every new feature introduced is usable in about every real world situation.  My current job is running with Informix containing a 5TB database and is still performing at top levels.

**What do you dislike about IBM Informix?**

It sometimes seems that Informix has been thrown to the back burner under IBM ownership but we do still see new releases so it has gotten better.

**Recommendations to others considering IBM Informix:**

If you want a robust system, Informix is the only way to go for ease of admin and setup.

**What problems is IBM Informix solving and how is that benefiting you?**

Serving results of clinical trials to a worldwide customer base with only one server.  The benefits of not having to deploy across multiple servers just to get performance increases is huge savings in the long run.

  ### 46. Informix - tough as nails

**Rating:** 5.0/5.0 stars

**Reviewed by:** Mike W. | Senior Database Consultant, Information Technology and Services, Small-Business (50 or fewer emp.)

**Reviewed Date:** April 10, 2015

**What do you like best about IBM Informix?**

A robust database product that is way ahead of the competition.  The incredible feature set and versatility makes it ideal as a back end workhorse supporting huge ERP systems and data warehouses, or as a small footprint database for Internet of Things applications, and everything in between.  The Informix Warehouse Accelerator produces is a game changer in terms of fast reporting against enormous data sets.  This database is everywhere, and you likely never even knew it - telecommunications, utilities, banking, retail...

**What do you dislike about IBM Informix?**

Not well known or publicized, despite its use around the world.  Small user community.  Incorrectly perceived as older technology.

**What problems is IBM Informix solving and how is that benefiting you?**

Data warehousing, and recently Internet of Things installations using TimeSeries on ARM processors.

  ### 47. A full featured, low cost, low administration, reliable and flexible database engine

**Rating:** 4.5/5.0 stars

**Reviewed by:** Alexandre M. | Senior IT Consultant, Mid-Market (51-1000 emp.)

**Reviewed Date:** July 15, 2015

**What do you like best about IBM Informix?**

Its confidence, availability, low cost, low adninistration, and wide range of  hardware architectures to install and run.

**What do you dislike about IBM Informix?**

Lack of product market and universities teaching Informix to base users

**Recommendations to others considering IBM Informix:**

Ask IBM for a certified and specialized Informix partner near you, to talk and discuss. You will not believe a single product has such wonderful features, that can boost your needs in a vrry ease process. Do not discard your hardware in each new product version.

**What problems is IBM Informix solving and how is that benefiting you?**

We have several customers from mid size to VLDB,. Informix is doing well in all of them, but companies that do not invest in development trainings make poor quality software.

  ### 48. Informix IDS is simply the best RDBMS I ever know

**Rating:** 5.0/5.0 stars

**Reviewed by:** Hamza Z. | Informix Consultant, Small-Business (50 or fewer emp.)

**Reviewed Date:** April 16, 2015

**What do you like best about IBM Informix?**

I definitely like it's architecture especiallly disk soace, memory and proces management. It implements a trully multithereading feature and you can see the parallelism in action. You can see also how Informix IDS deals with it's best friends, Unix and Linux systems.

**What do you dislike about IBM Informix?**

Most of clients using Informix are not aware of the benefits they can get from a well configured IDS engine, since it's works without the need of doing administrave tasks on it, I think that Informix developpers must focus on administration tools like OAT that wil make it easy to Informix users to know more about their RDBMS.

**What problems is IBM Informix solving and how is that benefiting you?**

I am working as a Consultant and all what I k,ow is that Informix has been deployed on huge companies around the world. I have seen for example a bank in Dubai with 600 users working on a database server with only 2GB of mamory.

  ### 49. A boot and forget, fast and reliable database management system 

**Rating:** 4.5/5.0 stars

**Reviewed by:** Philippe B. | ingénieur, Computer Software, Small-Business (50 or fewer emp.)

**Reviewed Date:** April 16, 2015

**What do you like best about IBM Informix?**

Informix offers a state of the art database management system, which is fast, reliable and very easy to maintain. At least for small to mid size databases like ours (< 1Tb) you barely have to do any administrative task.

**What do you dislike about IBM Informix?**

Language support for web development could be improved, with first class support and documentation for languages other than java and C/C++ 

**Recommendations to others considering IBM Informix:**

Don't pay too much attention to marketing (informix sucks at this) go for the technical aspects.
Minimal configuration, extended capabilities, performance.
Check revues for feedback on reliability.

**What problems is IBM Informix solving and how is that benefiting you?**

Informix powers our electronic health record product

  ### 50. Informix is "The Best" product available on the planet.

**Reviewed by:** Verified User in Information Technology and Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** April 08, 2015

**What do you like best about IBM Informix?**

Maintenance free database in the market,  just set it correctly and it will serve you for ever.  Runs mostly on all the Operating Systems available in the market.     

**What do you dislike about IBM Informix?**

Less work for DBAs, managers think if they really need any administrators. Cost factor and marketing which is not done properly. Also need to give free software to new vendors who implement their application on this database. 

**Recommendations to others considering IBM Informix:**

Honestly try Informix at least once to compare results with other competitor, and  you should able to make a decision.  If you don't have liberty of this test, just go for Informix and you will thank me for making this decision.  

**What problems is IBM Informix solving and how is that benefiting you?**

I support multiple clients from different industries in their business flow,  assist them reduce cost and keep the instance stable and online.  Also time to time suggest them of various new features available with the new versions.
