Serverless is great for developers who want to build an application end to end with lowest maintenance and financial cost. Serverless functions enable you to run your own code without maintaining the backend infra. But they are stateless by design so you need an external data store. So the next question is which databases are best fit for serverless? The good news is database vendors see the serverless trend and they are either launching either serverless offerings or trying to adapt their product. In this article, I will first list the things that make a database great for serverless. Then I ..read more

which compares the performance of leading serverless databases using a common web use case and serverless functions. The databases are DynamoDB, MongoDB (Atlas), Firestore, Cassandra (Datastax Astra), FaunaDB and Redis (Upstash ..read more

One of the best things about the serverless is its ability to scale even in case of huge traffic spikes. But unfortunately, scaling is not free both financially and technically. That’s why developers need to control their applications’ scalability. Here the main reasons you will need a rate limiting mechanism in your serverless application: There are many real life examples how an uncontrolled system can cause large bills. This is quite a risk for serverless applications thanks its highly scalable nature. Rate limiting will help you control these costs ..read more

Server side rendering is a great feature which helps you to write full stack applications. But if you are not careful, the performance of your Next.js website can be affected easily. In this blog post, I will explain how to leverage Redis to speed up your Next.js API calls. Before that I will briefly mention a simpler way to improve your performance ..read more

We are happy to announce Multi Zone Replication capability. When enabled the data is replicated to multiple availability zones. Multi zone replication provides you high availability and better scalability ..read more

Similar to Serverless functions (AWS Lambda etc.), Cloudflare Workers are stateless. As you can see in , developers are asking ways to connect their databases from Edge functions. Unfortunately, most databases are not designed for serverless environments, they require persistent connections. We developed the REST API over Redis to enable serverless edge functions to access Upstash in the simplest and fastest way possible ..read more

It is a common need to restrict access to your website to some specific IPs. In this post, I will show how to implement an IP Allow/Deny list using Edge computing. Let me first introduce Cloudflare Workers. are quite popular technology in recent years. It became in 2017 and Cloudflare KV storage became ..read more
