The phrase may seem a bit like a paradox but ‘serverless computing’ is attracting the attention of cloud heads for its simplicity. In the last few years, the cloud has become increasingly abstract, moving from IaaS to PaaS, and PaaS to the new serverless approach. Even though your code still runs on servers, it runs on servers that you won’t really have to pay any mind to. Below we take a look at ‘serverless computing’ and why this approach might be of interest to you.
Serverless is an event-based approach to programming and while it still uses servers, you won’t have to worry about server maintenance. Because this serverless platform takes care of provisioning and scaling automatically, you have ability to optimize your resources by making more efficient code. With serverless, your server hosted code, isn’t running all the time, only when the code is triggered by event that you’ve set up. Serverless also allows for the output of a function to be sent to another servic, so that it could be used to gather certain files to be sent to a specified database. While serverless works best in the cloud, it looks like the approach may soon make its way to PaaS and IaaS.offerings.
It all comes down to cost. In a recent analysis of serverless cloud pricing, Owen Rogers at 451 Research found that serverless clouds offer lower costs of ownerships than virtual machines and containers. The primary cost saving comes in the form of developer time because there’s no need to provision, configure, and manage the servers. The report compared serverless prices to those of the main cloud providers, AWS, Google, Microsoft, and IBM.
Who’s Using It?
Because serverless is best for new applications, so it makes sense that it’s been the approach of choice for new startups. However, serverless has recently been getting some attention from larger enterprises as well. For some businesses, this model just makes more sense financially, while also providing more flexibility.
What The Primary Benefits of Serverless?
What’s the point in going serverless if you won’t see significant benefits? There are a few key benefits in adopting serverless technology. Because developers aren’t deploying, managing, or scaling the servers, organizations are able to leave behind infrastructure administration. This decreases operational overhead. Another advantage of serverless is scalability. Upgrades are no longer reliant on DevOps teams and serverless applications can quickly and seamlessly scale up to accommodate heavy traffic. If you’re worried about security, serverless approaches help mitigate the risk of a DDoS attack and cuts down on the ability for hackers to target OS vulnerabilities.
