At AWS re:Invent this year, Matt Garman reminisced about the early days of AWS and how startups were the earliest adopters of the cloud. Enterprises followed suit, and now, the cloud has become a business imperative for all.
While all organizations big and small find value in the cloud, their requirements and expectations of the cloud can be very different. Cloud isn’t a one-size-fits-all, and luckily, we’re at a point where the market is brimming with cloud computing service providers, each offering unique value propositions.
However, with so many options, finding that perfect match can be gruelling. That’s why we’ve done the heavy lifting, so you don't have to. We’ve picked and ranked the top 10 cloud service providers—you’ll find a careful mix of providers of various sizes, niches, types, and expertise, all in a single place.
We’ve also compared these top cloud providers across key metrics like cost, scale, compliance, and innovation. Simply sift through our findings and zero in on the ones most suitable for your needs.
A cloud service provider (CSP) is a company that offers on-demand computing resources remotely over a network connection. The resources could be data storage, computing power, applications, infrastructure, and platform. Several CSPs have broadened their offerings by integrating proprietary and open-source tools and tailored services to meet the burgeoning demands of modern startups, SMBs, and enterprises.
The breadth of options available is truly impressive. However, navigating these diverse choices to find the ideal fit in terms of pricing, performance, services, flexibility, scalability, and more is challenging.
When choosing a cloud service provider, IT decision-makers must carefully consider their needs and constraints. Based on that, they can evaluate the vendor’s SLAs, the comprehensiveness of their service portfolio, the regions they operate in, cost dynamics, ease of use, and vendor lock-in risks. Another critical factor is the regional and industry-specific data regulations and laws that apply to them. A major challenge that enterprises, in particular, must address is integrating cloud solutions with their on-premise and legacy systems. The shortage of skilled talent can amplify this pain point.
It is crucial to consider all these factors for strategic decision-making that can future-proof cloud investments, and deliver quick and substantial returns while meeting immediate business needs. In our analysis, we have considered all these factors and pain points to give you a concrete starting point in your journey to finding and choosing the best cloud service provider(s) for your unique requirements and constraints.
For the sake of this analysis, we’ve focused on CSPs with public cloud offerings. However, you’ll also find hybrid vendors with strong private cloud offerings in our list. All providers we ranked have an outstanding reputation within their respective markets and niches and are known for reliability and uptime.
In addition to that, we have considered:
With that, let’s get right into it!
For most organizations, various workloads, data types, or business units align better with different cloud providers. Just because you’re centered on Microsoft’s productivity ecosystem and prefer Azure's deep integrations and convenience doesn’t mean you can’t use GCP for analytics or let your developers create cost-effective test environments fast in DigitalOcean.
Hybrid and multi-cloud are both viable options, with strong support from several vendors, as highlighted in our analysis. In fact, 80-90% of organizations end up choosing multiple CSPs. With a powerful, vendor-agnostic cloud management platform like emma, managing multiple cloud environments is a no-code breeze—even if your preferred CSPs aren't particularly supportive of multi-cloud.
