The
benefits of serverless computing include cost and time savings, development
flexibility, and increased performance, to name a few benefits. Is that enough
for companies to engage in serverless computing services? Tech Pro Research
conducted an online survey in April 2019 to find out. The survey asked the
following questions:
·
When does your organization plan to start using serverless
computing services?
·
Why has your organization decided not to use serverless
computing services?
·
Which cloud service provider do you currently use (or plan to
use) for your serverless computing needs?
·
What functions does your organization use serverless computing
for?
·
What benefits does your organization receive (or hope to
receive) from using serverless computing?
·
What issues has your company experienced with serverless
computing technology?
Of the
survey respondents, 47% currently use serverless computing services. More than
half (57%) use the service to develop web apps. Other functions mentioned by
respondents include business logic applications, support for database changes,
and executing batch jobs or scheduled tasks.
The
cloud service providers that respondents draw on for their serverless computing
needs are no surprise. The top three include AWS (49%), Microsoft Azure (36%),
and Google Cloud Platform (18%). Other industry heavyweights, including IBM
Cloud (1%) and Oracle Cloud Platform (2%), ranked substantially lower on the
survey in terms of meeting respondents' serverless computing needs.
The
availability of multiple cloud service vendors provides companies with plenty
of serverless computing options; however, 37% of respondents believe that their
choice for serverless computing provider has locked their enterprise into one
single vendor, potentially negating the flexibility they wanted in the first
place. The fact that no major vendors support a specific programming language
required by their enterprise is another obstacle mentioned by 17% of
respondents. In order to gain more supporters, the technology for serverless
computing must evolve to meet the needs of users.
These
drawbacks may influence potential users, as several respondents have not
deployed the service, despite its purported merits. According to the survey,
28% of respondents have no plans now nor in the future to use serverless
computing services, while 16% plan to use the service sometime beyond 12
months. Reasons for not utilizing serverless computing services range from
security and cost concerns to no apparent business need or uncertainty on how
to effectively apply the technology.
