Serverless: The Millennial Founder’s Guide to Lambda

As a founder, you’ll likely be looking at ways to cut IT costs and complexity. Huge rack servers all over your headquarters just wasn’t cutting it, so you moved to the cloud. But then you quickly realized that cloud bills can rack up fast and you have to pay for servers even when no one is using them!

Worst of all you now have to pay someone around to make sure that this server is available around the clock for when your customers need it. If only there was a way you could have these systems ready to go on standby only at the point your customer needs them and have them spin down so you don’t have to pay for them or maintain them when they’re not in use.

What is Serverless?

Serverless computing allows developers to build and run applications without having to manage any of the physical of software infrastructure that runs it. In a serverless setup, the cloud provider (such as AWS or Azure) automatically allocates resources as needed. This means you only pay for what you use, and there's no need to worry about server maintenance or capacity planning.

Pros and Cons of Serverless

Pros:

1. Cost Efficiency: Pay only for the compute time you consume, which can lead to significant cost savings.
2. Scalability: Automatically scales with the demand, handling spikes in traffic without manual intervention.
3. Reduced Operational Overhead: No need to manage servers or infrastructure, allowing your team to focus on development and innovation.
4. Faster Time to Market: Speeds up the development process as developers can focus on writing code instead of managing infrastructure.

Cons:

1. Cold Start Latency: Initial request to a serverless function can be slower due to the time it takes to spin up the instance.
2. Limited Execution Time: Functions typically have a maximum execution time, which can be a limitation for long-running tasks.
3. Vendor Lock-in: Moving from one cloud provider to another can be challenging due to proprietary services and features.
4. Debugging and Monitoring: Troubleshooting issues can be more complex compared to traditional server-based environments.

Best Use Cases for Serverless

1. Event-Driven Applications: Ideal for applications that respond to events such as file uploads, database updates, or API calls.
2. Microservices: Suitable for breaking down complex applications into smaller, manageable, and independent services.
3. Real-Time Data Processing: Perfect for processing streams of data in real-time, such as IoT data or logs.
4. Web Applications: Great for serving web applications where the backend logic is executed based on user actions.

Introducing AWS Lambda and Azure Functions

AWS Lambda: AWS Lambda is a serverless compute service from Amazon Web Services. It lets you run code without provisioning or managing servers. Lambda functions can be triggered by various AWS services or custom events, and you only pay for the compute time that you actually use.

Azure Functions: Azure Functions, from by Microsoft Azure, offers similar serverless compute capabilities. It supports a wide range of programming languages and integrates seamlessly with other Azure services. Azure Functions also supports both event-driven and scheduled executions.

What This Means for Your Company

Lower Costs: By leveraging serverless computing, you can significantly reduce infrastructure costs since you only pay for what they use. This can be particularly good for startups and small businesses with variable workloads.

Less Maintenance: Serverless removes the need for server management, freeing up your IT team to focus on delivering business value rather than maintaining infrastructure. This leads to improved productivity and faster innovation cycles.

Scalability: Serverless solutions automatically scale with your application’s needs, ensuring optimal performance without manual intervention. This is particularly beneficial during peak times, such as product launches or marketing campaigns.

Improved Agility: With serverless, your development team can quickly deploy new features and upgrade existing ones, reducing the time to market and allowing you to stay ahead of competitors.

In conclusion, serverless computing, with AWS Lambda and Azure Functions, offers a compelling solution for digitally competitive businesses looking to optimize costs, reduce strain on Human Resources, and accelerate innovation. By understanding the pros, cons, and when to use and not to use serveless, you can make informed decisions that align with business objectives and drive success.
