Every cloud-based solution brings the promise of considerable savings. Serverless is yet another breakthrough in IT solutions.
The idea behind serverless is to enable payment exclusively for the resources that you actually use. Calculated with extreme accuracy. It allows achieving impressive savings, which remained beyond grasp during all the years of implementing cloud solutions. No other solution than serverless allows unlimited use of resources without prior planning or infrastructure management. Everything remains in the hands of the supplier, whilst you can use their resources smoothly. You buy only as resources as you currently need. Sounds good, doesn’t it?
The very essence of serverless brings you the promise of not worrying about access to a server and its resources. To a much greater extent and in a much more convenient manner than in case of the popular IaaS (Infrastructure as a Service). It’s the provider’s role to take care of adequate server space alongside with fulfilling the tasks regarding the application you are developing. As a matter of fact serverless consists in hosting tiny fragments of code, which perform certain tasks for you. Serverless does the planning and resource management on your behalf so as to rise up to the computing-related challenges.
Every business in the serverless model
The first solution of this kind was Lambda from AWS (Amazon Web Services), which still today is the leader on serverless solutions.
– Serverless is an approach that is growing the most on AWS (Amazon Web Services) and Microsoft. We can see that its hard to utilize the advantages of Serverless without using the big Public Cloud factories. These are global providers with multiple Serverless solutions that prove to work on every market regardless of the scale of business – says Ola Hesselroth, Partner at Euvic.
Both Lambda from AWS and Microsoft Azure dominate the market and are a starting point for developing applications of their clients. It’s the largest companies that dominate among providers of cloud-based services.
According to Garner, in 2016 the 10 top providers had a 50% share in the IaaS market, yet by 2021 their share will rise to almost 70%.
Bearing in mind the specific character of this solution, you may find a few key advantages for the developers using serverless:

Serverless ensures you use only such resources that you really need. It’s worth remembering that serverless is dedicated to all the business solutions, not only the fledgling ones.
– It’s true that due to its specific characteristics and the direct advantages it brings, this approach is most often mentioned in the context of start-ups. However, serverless can be implemented in any organization, regardless of the scale of its business. Process efficiency always remains the top priority alongside with the product, service or application, which is to be provided using the serverless approach. Therefore, an innovative offer and organizational culture centered around unique products are a starting point. Only once we have a product we wish to develop or use, we can choose between AWS and Azure, and implement “serverless” – says Ola Hesselroth from Euvic.
Due to the very nature of these solutions, it’s frequently suggested that name „serverless” should be replaced with a more suitable „FaaS”, i.e. „Function as a Service”. After all, we are not getting rid of servers, but merely freeing ourselves from the responsibility of managing their resources and limiting points of contact with them. This solution has been achieved through multiple stages of evolution of cloud-based solutions. Increasingly fine-tuned to suit clients’ business needs. Companies’ demands – regardless of their size or the market segment they operate in – are continuously growing. Gartner estimates that the public cloud market will be worth $186 billion globally whereas the value of the IaaS segment will rise by over 35%, reaching almost $41 billion at the end of 2018.
