IaaS, or infrastructure as a service, is a cloud computing model that outsources IT infrastructure. IaaS providers purchase and manage expensive, physical computing resources while providing a wide range of cloud services in return. Companies essentially rent out the provider’s processing power to virtualize servers, store data, and facilitate network traffic.
IaaS is typically considered the most bare bones offering model for cloud-based solutions. IaaS provides a wider range of functionality and customization compared to cloud platform as a service (PaaS) and software as a service (SaaS) offerings. IaaS delivers computing power and management capabilities, while PaaS and SaaS provide a range of prebuilt tools and applications.
IaaS offerings allow businesses to create and utilize virtual hardware tools without buying, building, or hosting them. These tools are provided externally as virtualized servers, databases, or bandwidth, as well as other tools.
Key Benefits of Infrastructure as a Service
IaaS solutions can be a great fit for all businesses. For example, small businesses can avoid the costly process of building or buying in-house software solutions by using IaaS solutions. These tools can require heavy maintenance, but are managed by the service provider rather than the small business. Instead of hosting the tools onsite, they are distributed through multiple data centers and maintained by the IaaS provider.
IaaS solutions are ideal for growing businesses. They are highly scalable and are offered on a pay-per-use basis. This means that companies don’t have to worry about surprises in cost. As the company grows and utilizes an existing plan, they are already presented with the price for additional usage.
Small businesses with limited physical resources can subscribe to an IaaS solution and multiply their potential infrastructure. New, larger databases allow companies to use scalable storage solutions. Virtual desktops enable customers to utilize products across any platform. Companies are also provided with as much bandwidth as they need.
If a company has limited staff or time, they can also benefit from the automation of multiple tasks. This includes IT administrative duties, deployments, application monitoring, and others (depending on the provider). Providers control resources to optimize a company’s services or an application’s productivity.
Tech companies developing new software can benefit from IaaS solutions significantly during the development and testing phases. Application hosting and testing can be much cheaper through remote servers than through self-hosting. Users are able to test and deploy a tool multiple times without requiring in-house servers. They can then either keep an application hosted remotely or deploy it on in-house resources once the application is ready to be made publicly available.
It is common for IT departments to use a patchwork of IaaS solutions to manage web applications across multiple environments. However, this complex architecture needs to be evaluated constantly to maintain efficiency and meet business goals. Deciding between using public, private, or hybrid clouds usually comes down to performance and cost.
Public – Public clouds are the most cost-effective route when choosing an IaaS provider, as they allow businesses to reduce upfront spending on hardware and maintenance costs. Technical benefits of public cloud options include: scalability, reliability, and broader feature sets. Public cloud options are popular among startups and small businesses; however, they may not be the best fit for businesses operating in industries regulated by data security laws (HIPAA, PCI, etc.).
Private – Private clouds offer better security and compatibility for legacy web applications, as well as an easier migration process than public clouds. Private clouds can be housed in on-site data centers; however, most mid-market to enterprise-level businesses that use private clouds opt to use third-party IaaS service providers. Private clouds are popular among businesses in industries such as finance, health care, and commerce, where data security is held to a higher standard than in other industries.
Hybrid – Hybrid clouds provide a combination of the two options mentioned above. Hybrid clouds are popular among large enterprises and other businesses looking to find common ground between security and cost. This approach to IaaS allows businesses to process certain parts of a web application in a public cloud while storing and processing confidential data in a private cloud.
Virtual Machines – Provides virtualized networks, applications, and operating systems. IaaS solutions deliver emulated tools using the provider’s physical resources. VMs expand a user’s access to operating systems and host environments without requiring expensive hardware.
Storage Management – Provides management tools for data storage, database configuration, and scaling. IaaS solutions give users access to a variety of databases and cloud storage applications that scale as use increases. Cloud-based storage can become especially important for preventing data loss.
Networking – Lets users provision networks, deliver content, balance loads, and manage traffic. Networking features allow users to choose how data is connected and networks are communicating.
Cloud Migration – Allows transferring data and virtual machines during adoption and maintenance. The digital transformation has caused many businesses to shift from on-premise infrastructure to cloud-based solutions. Cloud migration tools simplify and expedite the process of transferring systems to the cloud.
Analytics – Lets users analyze storage, performance, and connectivity. Analytics features can help optimize performance for users by managing traffic and resource allocation. Some IaaS solutions also have big data analytics features to help users process enormous data sets.
Maintenance – Enables maintenance to existing virtual machines to improve functionality and security. Maintenance features help users centralize control over their users, their endpoints, and the virtual machines they access.
Database Management — Supports managing different types of databases and integration methods. Database support can give users access to your cloud databases and sync them to facilitate live updates.
Security – During your evaluation process, you will need to take into consideration the data you plan on processing in your IaaS solution. Sensitive data such as intellectual property, medical records, and payment information require strict security controls. As regulations like the Payment Card Industry Data Security Standard (PCI DSS) and Health Insurance Portability and Accountability Act (HIPAA) dictate how confidential data is stored and transferred, businesses governed by these will have to make sure their IaaS provider can meet these standards.
Existing infrastructure – Businesses with existing cloud infrastructure will have to consider the cost and effort necessary to migrate to or integrate with a new cloud solution. While migrating to a private cloud can be easier for businesses with existing infrastructure, public clouds offer broader feature sets and lower costs. Furthermore, several IaaS providers offer entire ecosystems around their solutions which can also influence buying decisions.
