Serverless architecture is a cloud computing execution model where the cloud provider dynamically manages the allocation and provisioning of servers. In this article, we delve into the significance of serverless architecture, exploring its origins, pivotal benefits, and the transformative impact it has had on modern software development and deployment strategies.
Origin of serverless architecture
The genesis of serverless architecture can be traced back to cloud computing’s evolution. Initially, cloud computing offered the ability to rent virtual machines, but this still required users to manage these machines. The desire for more efficient computing models led to Platform as a Service (PaaS), which abstracted and managed more of the infrastructure.
The true inception of serverless came with the launch of AWS Lambda in 2014. This service allowed developers to run code without provisioning or managing servers, marking a significant departure from traditional server-based architectures. It wasn’t just about running serverless functions; it was a new way of thinking about resource utilization and scalability.
Why serverless architecture is important
- Cost Efficiency: Serverless computing follows a pay-as-you-go model. Costs are based on actual consumption rather than pre-purchased capacity. This model can lead to significant cost savings, as users are not paying for idle server space.
- Scalability: Serverless architecture provides automatic scaling. As the application demand increases, the architecture seamlessly scales up to meet the demand and scales down when demand decreases, ensuring efficient resource utilization.
- Increased Developer Productivity: Developers can focus more on writing code and less on managing and operating servers or runtime environments. This shift enhances productivity, as it reduces the operational overhead involved in deploying and maintaining infrastructure.
- Improved Latency: By utilizing function instances that are closer to the end user, serverless architecture can reduce latency. This proximity improves application performance, providing a better user experience.
- Quick Deployments and Updates: Serverless architectures facilitate easier and quicker deployment of applications and updates. Smaller, independent functions can be deployed without affecting the entire system, allowing for continuous integration and continuous delivery (CI/CD) practices.
- Eco-Friendly Computing: With more efficient resource utilization, serverless computing can be seen as a greener alternative. It optimizes energy usage, as there are no idle servers consuming unnecessary energy.
Next we take a look at some of the companies that have successfully implemented serverless architecture…and ripped the benefits!
Companies using serverless architecture
These examples not only demonstrate the versatility of serverless architecture but also highlight its benefits in terms of cost efficiency, scalability, and performance.
- Netflix: One of the most prominent examples is Netflix, which uses serverless technology for transforming media content. They set up pipelines with serverless functions to convert and provide media content in over 50 different formats to their vast customer base. This approach serves more than 70 billion hours of content efficiently.
- Coca-Cola: Coca-Cola implemented serverless architecture for their global network of vending machines. This transition resulted in significant cost savings. They reduced their operating costs from $12,864/year to $4,490/year, a substantial decrease for managing 30 million requests. This serverless framework also supports marketing campaigns and transaction handling.
- Thomson Reuters: This global news and information company uses serverless architecture to process up to 4,000 events per second for its usage analytics service. The service, deployed using AWS, reliably handles traffic spikes and was put into production in just five months.
- iRobot: Known for its Roomba robotic vacuum, iRobot employs a serverless architecture to develop connected devices for smart homes. Their platform, which is managed by fewer than ten people, is based on AWS Lambda and AWS IoT.
- FINRA: The Financial Industry Regulatory Authority (FINRA) uses serverless architecture to analyze 75 billion market events daily. This system aids in identifying fraud and insider trading.
- Autodesk: The software company created Tailor to manage its AWS accounts using a serverless architecture. This system was operational in just one month, showcasing the rapid deployment capabilities of serverless solutions.
- Financial Engines: As the largest independent investment advisor in the US, Financial Engines moved its core platform to a serverless architecture. This shift resulted in cost savings, zero downtime, and the ability to handle 60,000 requests per minute.
- Major League Baseball Advanced Media (MLBAM): MLBAM uses serverless architecture for its product Statcast, which delivers real-time gameplay data to broadcasters. This approach enhances data processing and delivery capabilities.
- Square Enix: The gaming company implemented serverless architecture for image processing in its MMORPGs. This reduced image processing time from hours to just over 10 seconds and lowered infrastructure costs while handling traffic spikes effectively.
- The Guardian: This renowned publishing company uses serverless architecture to create new internal business workflows and orchestrate data across systems. AWS Step Functions and AWS Lambda functions facilitate these processes.
- Benchling: A life science software company, Benchling, used serverless architecture for its CRISPR research platform. This enabled increased scalability and reduced costs, allowing researchers to focus more on their work without performance limitations.
- T-Mobile: The telecommunications giant has a “serverless first” policy for developing new services. Serverless technologies like AWS Lambda play a crucial role in their mission-critical applications, catering to over 70 million customers.
These examples underscore the transformative impact of serverless architecture across diverse sectors, enhancing efficiency, reducing costs, and streamlining operations.
Challenges and the future
Despite its advantages, serverless computing isn’t without challenges. Concerns around security, vendor lock-in, and limitations in long-running processes exist. However, the continuous evolution of this technology promises to address these challenges.
As cloud computing continues to evolve, serverless architecture is likely to play an increasingly important role. Its influence extends beyond cost savings and operational efficiency; it represents a fundamental shift in how software is developed and deployed, pointing towards a more efficient and scalable future in the digital world.
