Eliminating cold starts with Cloudflare Workers

A “cold start” is the time it takes to load and execute a new copy of a serverless function for the first time. It’s a problem that’s both complicated to solve and costly to fix. Other serverless platforms make you choose between suffering from random increases in execution time, or paying your way out with synthetic requests to keep your function warm. Cold starts are a horrible experience, especially when serverless containers can take full seconds to warm up.

Unlike containers, Cloudflare Workers utilize isolate technology, which measure cold starts in single-digit milliseconds. Well, at least they did. Today, we’re removing the need to worry about cold starts entirely, by introducing support for Workers that have no cold starts at all – that’s right, zero. Forget about cold starts, warm starts, or… any starts, with Cloudflare Workers you get always-hot, raw performance in more than 200 cities worldwide.

Why is there a cold start problem?

It’s impractical to keep everyone’s functions warm in memory all the time. Instead, serverless providers only warm up a function after the first request is received. Then, after a period of inactivity, the function becomes cold again and the cycle continues.

For Workers, this has never been much of a problem. In contrast to containers that can spend full seconds spinning up a new containerized process for each function, the isolate technology behind Workers allows it to warm up a function in under 5 milliseconds.

_Learn more about how isolates enable Cloudflare Workers to be performant and secure _here.

Cold starts are ugly. They’re unexpected, unavoidable, and cause unpredictable code execution times. You shouldn’t have to compromise your customers’ experience to enjoy the benefits of serverless. In a collaborative effort between our Workers and Protocols teams, we set out to create a solution where you never have to worry about cold starts, warm starts, or pre-warming ever again.

How is a zero cold start even possible?

Like many features at Cloudflare, security and encryption make our network more intelligent. Since 95% of Worker requests are securely handled over HTTPS, we engineered a solution that uses the Internet’s encryption protocols to our advantage.

Before a client can send an HTTPS request, it needs to establish a secure channel with the server. This process is known as “handshaking” in the TLS, or Transport Layer Security, protocol. Most clients also send a hostname (e.g. cloudflare.com) in that handshake, which is referred to as the SNI, or Server Name Indication. The server receives the handshake, sends back a certificate, and now the client is allowed to send its original request, encrypted.

Previously, Workers would only load and compile after the entire handshake process was complete, which involves two round-trips between the client and server. But wait, we thought, if the hostname is present in the handshake, why wait until the entire process is done to preload the Worker? Since the handshake takes some time, there is an opportunity to warm up resources during the waiting time before the request arrives.

With our newest optimization, when Cloudflare receives the first packet during TLS negotiation, the “ClientHello,” we hint the Workers runtime to eagerly load that hostname’s Worker. After the handshake is done, the Worker is warm and ready to receive requests. Since it only takes 5 milliseconds to load a Worker, and the average latency between a client and Cloudflare is more than that, the cold start is zero. The Worker starts executing code the moment the request is received from the client.

Serverless Applications - Pros and Cons to Help Businesses Decide - Prismetric

In the past few years, especially after Amazon Web Services (AWS) introduced its Lambda platform, serverless architecture became the business realm’s buzzword. The increasing popularity of serverless applications saw market leaders like Netflix, Airbnb, Nike, etc., adopting the serverless architecture to handle their backend functions better. Moreover, serverless architecture’s market size is expected to reach a whopping $9.17 billion by the year 2023.

Why use serverless computing?
As a business it is best to approach a professional mobile app development company to build apps that are deployed on various servers; nevertheless, businesses should understand that the benefits of the serverless applications lie in the possibility it promises ideal business implementations and not in the hype created by cloud vendors. With the serverless architecture, the developers can easily code arbitrary codes on-demand without worrying about the underlying hardware.

But as is the case with all game-changing trends, many businesses opt for serverless applications just for the sake of being up-to-date with their peers without thinking about the actual need of their business.

The serverless applications work well with stateless use cases, the cases which execute cleanly and give the next operation in a sequence. On the other hand, the serverless architecture is not fit for predictable applications where there is a lot of reading and writing in the backend system.

Another benefit of working with the serverless software architecture is that the third-party service provider will charge based on the total number of requests. As the number of requests increases, the charge is bound to increase, but then it will cost significantly less than a dedicated IT infrastructure.

Defining serverless software architecture
In serverless software architecture, the application logic is implemented in an environment where operating systems, servers, or virtual machines are not visible. Although where the application logic is executed is running on any operating system which uses physical servers. But the difference here is that managing the infrastructure is the soul of the service provider and the mobile app developer focuses only on writing the codes.

There are two different approaches when it comes to serverless applications. They are

Backend as a service (BaaS)
Function as a service (FaaS)

1. Backend as a service (BaaS)
   The basic required functionality of the growing number of third party services is to provide server-side logic and maintain their internal state. This requirement has led to applications that do not have server-side logic or any application-specific logic. Thus they depend on third-party services for everything.

Moreover, other examples of third-party services are Autho, AWS Cognito (authentication as a service), Amazon Kinesis, Keen IO (analytics as a service), and many more.

2. Function as a Service (FaaS)
   FaaS is the modern alternative to traditional architecture when the application still requires server-side logic. With Function as a Service, the developer can focus on implementing stateless functions triggered by events and can communicate efficiently with the external world.

FaaS serverless architecture is majorly used with microservices architecture as it renders everything to the organization. AWS Lambda, Google Cloud functions, etc., are some of the examples of FaaS implementation.

Pros of Serverless applications
There are specific ways in which serverless applications can redefine the way business is done in the modern age and has some distinct advantages over the traditional could platforms. Here are a few –

🔹 Highly Scalable
The flexible nature of the serverless architecture makes it ideal for scaling the applications. The serverless application’s benefit is that it allows the vendor to run each of the functions in separate containers, allowing optimizing them automatically and effectively. Moreover, unlike in the traditional cloud, one doesn’t need to purchase a certain number of resources in serverless applications and can be as flexible as possible.

🔹 Cost-Effective
As the organizations don’t need to spend hundreds and thousands of dollars on hardware, they don’t need to pay anything to the engineers to maintain the hardware. The serverless application’s pricing model is execution based as the organization is charged according to the executions they have made.

The company that uses the serverless applications is allotted a specific amount of time, and the pricing of the execution depends on the memory required. Different types of costs like presence detection, access authorization, image processing, etc., associated with a physical or virtual server is completely eliminated with the serverless applications.

🔹 Focuses on user experience
As the companies don’t always think about maintaining the servers, it allows them to focus on more productive things like developing and improving customer service features. A recent survey says that about 56% of the users are either using or planning to use the serverless applications in the coming six months.

Moreover, as the companies would save money with serverless apps as they don’t have to maintain any hardware system, it can be then utilized to enhance the level of customer service and features of the apps.

🔹 Ease of migration
It is easy to get started with serverless applications by porting individual features and operate them as on-demand events. For example, in a CMS, a video plugin requires transcoding video for different formats and bitrates. If the organization wished to do this with a WordPress server, it might not be a good fit as it would require resources dedicated to serving pages rather than encoding the video.

Moreover, the benefits of serverless applications can be used optimally to handle metadata encoding and creation. Similarly, serverless apps can be used in other plugins that are often prone to critical vulnerabilities.

Cons of serverless applications
Despite having some clear benefits, serverless applications are not specific for every single use case. We have listed the top things that an organization should keep in mind while opting for serverless applications.

🔹 Complete dependence on third-party vendor
In the realm of serverless applications, the third-party vendor is the king, and the organizations have no options but to play according to their rules. For example, if an application is set in Lambda, it is not easy to port it into Azure. The same is the case for coding languages. In present times, only Python developers and Node.js developers have the luxury to choose between existing serverless options.

Therefore, if you are planning to consider serverless applications for your next project, make sure that your vendor has everything needed to complete the project.

🔹 Challenges in debugging with traditional tools
It isn’t easy to perform debugging, especially for large enterprise applications that include various individual functions. Serverless applications use traditional tools and thus provide no option to attach a debugger in the public cloud. The organization can either do the debugging process locally or use logging for the same purpose. In addition to this, the DevOps tools in the serverless application do not support the idea of quickly deploying small bits of codes into running applications.
