There is a lot of buzz around the emergence of serverless technology. What exactly are the opportunities and challenges it brings? More importantly, what are the implications for the future of cloud computing?
We will walk you through the implications, benefits, and challenges of serverless technology as well as how second generation platforms mitigate these challenges.
This is the second post in our Serverless Series where we've been exploring a variety of questions about this emerging technology. In our first post, we discussed the history and evolution of serverless computing. Check it out here if you missed it: From Cloud Computing to Serverless: The rise of new paradigms.
Going serverless has many more powerful and profound implications than what may be understood at first glance. This transition is architectural, cost-effective, and strategic:
With all that being said, here is a breakdown of the benefits and challenges of going serverless as well as considerations and recommendations for when to go serverless.
Serverless technologies bring technical benefits that result in significant business gains. A lot of the benefits of serverless are related. Below is a table we prepared to highlight the core benefits of serverless and analyze their corresponding technical and business implications.
|Aspect of Serverless Technology||Technical Benefit||Resulting Business Advantage|
|Autoscaling of Servers||Traffic variation is handled by the serverless provider who scales the servers automatically.||Increased availability of your platforms, reduced latency for end-users, which means less customer churn and ultimately increased revenue for the business.|
|Reduced Staff Costs||Reduced dependencies of DevOps & SRE competencies and tasks.||Staff cost reduction, workaround for the hiring challenge, and better use of developers who shouldered SRE burdens.|
|Deployment Velocity||Greater deployment velocity for your projects and applications because there is less architecture and capacity planning.||Faster time-to-market for new products, features, and updates.|
|No Infrastructure Management||0 server maintenance and updates mean more time to focus on business logic.||Refocusing time, manpower, and money into your business.|
|Pay as you Grow||Reduced capacity planning burden for technical team members.||Lower IT costs from the granular pricing model and an overall more efficient allocation of financial resources.|
We strongly believe modern applications will be serverless in their design and that most greenfield applications should plan to run on the serverless model. These new applications will be fast to deploy, autoscaling, and easy to update thanks to the advantages offered by serverless platforms.
As a result of the aforementioned benefits, businesses adopting the serverless model will certainly gain a competitive advantage compared to those who are slow to adopt serverless.
With first-generation platforms, migrating existing or legacy applications to a serverless model may not be the most effective or efficient solution. Koyeb is a next-generation serverless platform dedicated to facilitating the serverless experience.
The table below lists the existing challenges to serverless, which firms must consider before transitioning to serverless technologies, as well as how Koyeb provides solutions to these traditional serverless pain points.
|Aspect of Serverless Technology||Challenge||Koyeb's Mitigation|
|Cold-start||Performance issues such as cold starts and timeouts for long-running tasks.||Koyeb’s stack is optimized to drastically reduce container boot time and provides a simple way to reduce latency to zero for highly latency-sensitive applications.|
|Cost Control||Vulnerability to Denial-of-Wallet attacks||Koyeb users can set billing alerts to receive notifications for high levels of traffic. Moreover, Koyeb's transparent billing model makes it easy to understand your costs.|
|Learning Curve||Overcoming the serverless learning curve by becoming familiar with and adapting the best practices for serverless.||Koyeb offers a range of learning resources, including guides, tutorials, blog posts, to help developers overcome the learning curve.|
|Lack of Portability||Serverless solutions are not interoperable.||With Koyeb, you can seamlessly deploy any containerized app.|
|Long-Running Tasks||Limitations surrounding software configuration and execution.||No timeout on your executions, Koyeb is designed to handle both short and long-running tasks.|
|Lack of Control of the Underlying Infrastructure||With outsourcing the underlying infrastructure, there is an inherent level of control relinquished of the underlying infrastructure.||Koyeb offers a lot of hardware resource variants to run any workloads on high-end hardware.|
|Observability||Monitoring and troubleshooting are pain points for those adopting serverless.||Koyeb offers logs to provide visibility into your workloads. Moreover, we are compatible with other solutions offered in the serverless ecosystem.|
