Top Cloud Service Providers & Companies | eWEEK – eWeek

Cloud computing providers play a foundational role for businesses. Virtually every enterprise uses cloud computing in some manner, whether it’s to deliver key infrastructure and services, host applications or a content delivery network (CDN), or handle machine learning and software development.

The convenience and economics of cloud providers make them increasingly appealing. Cloud deployments are:

  • Typically fast and easy to provision
  • Deliver enormous flexibility and are always-on
  • Boost speed and performance
  • Move organizations away from a cash-intensive CAPEX model toward a more budget-friendly OPEX framework

Cloud frameworks also support an array of emerging digital technologies, mobility, artificial intelligence (AI) and machine learning (ML), and the Internet of Things (IoT). As networks expand, the edge becomes more important, and a greater need to manage data in an agile way takes shapes, clouds delivery evolutionary and sometimes revolutionary gains.

According to Gartner, the worldwide public cloud services market grew 40.7% in 2020. “Hyperscale providers are continuing to build distributed cloud and edge solutions that extend the public cloud’s reach into private and on-premises locations, addressing the needs of organizations relating to data sovereignty, workload portability and network latency,” noted Sid Nag, research vice president at Gartner.

How to Select the Best Cloud Provider

With so many vendors and choices, selecting a cloud computing provider can prove daunting. There are numerous factors to consider, including the type of services to use, how to integrate Infrastructure-as-a-service (IaaS), Platform-as-a-Service (PaaS) and/or Software-as-a-Service (SaaS), and whether to use public or hybrid clouds – or both.

Understanding cloud features and options, performance, availability, pricing, security and compatibility with other software and systems is also vital. Your organization may need to use a more complex multi-cloud framework.

As a result, it’s crucial to understand your organization’s needs, what cloud frameworks make sense, and which vendors are the best fit for your business model and specific requirements. It’s also wise to understand the cloud provider’s vision, its roadmap and its commitment to service and support.

Here are some key things to focus on if you’re in the market for cloud infrastructure and platform software:

  • What does your organization require? Different cloud platforms are better suited to different organizational requirements—and geographic footprints vary greatly. Similarly, different platforms focus on different services. A few of the factors to consider include your dependency on legacy systems currently in place, the type of cloud services needed, the applications and services they support, security and compliance requirements, and overall scalability and flexibility.
  • What does the pricing model look like? Not surprisingly, pricing varies greatly among vendors. A cloud provider may be a more economical fit, based on the specific needs of your organization. However, it’s critical to look beyond the basic price tag and understand the total cost of integrating the cloud into existing services and applications, and what overall value it delivers.
  • What is the vendor’s commitment to performance and availability? All cloud providers promise high availability, but not all availability is the same. You may need 2 nines (99.99 percent) or up to 5 nines (99.999), depending on the use case and the level of resiliency required. No less important: make sure you understand the service level agreement (SLA) before signing on the dotted line. How does it ensure availability after a natural disaster or system failure? What will the vendor do if it fails to meet promised standards?
  • What is the vendor’s commitment to security? This includes several critical areas: physical protections for data centers, cybersecurity standards and protections the vendor has in place, accreditations, compliance, SLAs, legal protections and compensation if something goes astray. In addition, it’s essential to know how and where data is stored.
  • What is the vendor’s roadmap and what is its commitment to support? Although a vendor may offer products and services you need today, there’s no sure bet that this will be the case next year. Or that it will be the best platform for your needs. You can reduce the turbulence of any future changes by understanding the vendor’s roadmap, its commitment to support, but also how easy it is to change cloud providers, if this becomes necessary.
