What workloads run best on which clouds?

Cloud computing workloads are spread relatively evenly across public, private and private platforms from the major players – Amazon Web Service, Microsoft Azure and Google Cloud Platform (GCP), though what jobs runs on what platforms tends to vary, according to a new report from TECHnalysis Research.

Of the 600 medium and large U.S.-based organizations using cloud for several years, 40% of workloads are run in a public cloud, 31% in an on-premise legacy environment and 29% in a private or hybrid cloud. cloud. The top cloud platforms were Azure at 72%, AWS and GCP at 53% and IBM with 47%.

The most popular workloads across all three approaches are: databases, analytics and web/content hosting.

The mix of cloud workloads varies by provider, though. For example, while databases are No. 1 on Azure and GCP, the top workload on AWS is web/content hosting, as shown here:

Other key takeaways from the report include:

  • Top software-as-a-service applications: Microsoft Office 365 (68% of respondents), Microsoft SharePoint (42%) and Google G Suite (37%).
  • Top factors in selecting cloud providers (no percentages given): quality of management tools, quality of programming tools, price.
  • Top reasons for moving to cloud: performance improvements (36%), cost savings (32.9%), create new products or services (31.8%).
  • Top reasons for not moving to cloud: security (52.5%), regulatory requirements (43.7%), lack of internal development skills (42.3%).

On the latter two findings, Technalysis President Bob O'Donnell said, "The top reasons that survey respondents gave for migrating workloads to the cloud are to improve performance, to increase security, and because of the need to modernize applications. Cost savings actually came in fourth. Ironically, the top reasons those same companies cited for not moving some of their applications to the cloud were very similar: security concerns, performance challenges, regulatory requirements and costs. These dichotomies highlight the ongoing challenges and opposing forces that are a regular part of the modern cloud computing landscape."
