Serverless Visitor Counter Badge with Azure Functions

,

We all love web badges. You might have spotted many of them in README of repositories, including the repository of my blog, The Cloud Blog. In general, web badges serve two purposes.

  1. They are visually appealing.
  2. They display key information instantly.

If you scroll to my website’s footer section, you will find GitHub and Netlify badges that display the status of the latest build and deployment. I use them to quickly check whether everything is fine with the world without navigating to their dashboards. In essence, a badge is an SVG image with dynamic content embedded in it.

Serverless vs. Microservices Architecture: Is this the Future of Business Computing?

,

Serverless computing, which is commonly referred to as just Serverless, is a promising cloud-based technology model that has emerged on the app development and software architecture horizon in recent years. Trying to avail themselves of the huge serverless framework potential, many big-time market players have been quick to jump on the cloud services bandwagon. Such software giants like Google, Microsoft, IBM, and Amazon already offer the customers to migrate all the local business operational efficiencies to be hosted on their flagship serverless platforms like AWS Lambda and Azure Functions.   

Simply put, serverless architecture is an event- and request-driven tech solution allowing application developers to create actionable working environments in the cloud that have all the necessary computational resources needed for a smooth coding flow. This framework comes in handy especially when time is an issue and the tasks assigned are quite resource-intensive.

Serverless: The New Frontier of Web Services. Do or Don’t?

,

Cloud management has come a long way, beginning with physical hardware, and then moving servers to the cloud.  It seems likely that the next logical step is to run code serverless! Without needing to manage hardware or depend on infrastructure providers like Google and Amazon, serverless can run code in a managed service container, completely unaffected by server-level issues. By utilizing this new step, you won’t have to worry about operating systems, web servers, or even updates. 

Although it seems like a no-brainer, there are a number of things you both lose and gain when switching over. The benefits alone should be enough to get you interested; you do the work, create an application, and once your code is uploaded you are promised simplicity, low cost, and automatic scaling. Due to the fact that the service provider is automatically managed, scaling is much faster. In addition to this, you only pay for what you use, cutting back on the normal cost, and saving you or your company money. This situation seems ideal, but there are also drawbacks to serverless that can complicate your decision.

AWS KMS Use Case With Serverless Application Model (SAM): An End To End Solution

,

The Basics

AWS KMS is a Key Management Service that lets you create Cryptographic keys that you can use to encrypt and decrypt data and also other keys. You can read more about it here.

Important Points About Keys

Please note that the CMK generated can only be used to encrypt a small amount of data like passwords, RSA keys. You can use AWS KMS customer master keys (CMKs) to generate, encrypt, and decrypt data keys. However, AWS KMS does not store, manage, or track your data keys, or perform cryptographic operations with data keys.

Running the Nanos Unikernel Inside Firecracker

,

A lot of people seem to be under the impression that Firecracker is a competing technology against unikernels. It actually isn’t. It’s more of an alternative to existing machine monitors such as qemu and is actually complementary if you need the quick boot times. As for isolation levels you are going to have about the same isolation as you would get with KVM – it uses the same facilities underneath.

OSv was the first unikernel to have support for Firecracker but now Nanos has support as well.

Cutting Step-Functions Costs on Enterprise-Scale Workflows

,

AWS Step Functions is a great service for orchestrating multi-step workflows with complex logic. It’s fast to implement, relatively easy to use and just works. The problem is its price.

For relatively low-scale projects, it’s a feasible solution. But for large-scale, enterprise-grade orchestration with hundreds of millions of processes, each with dozens of steps, it can be cost-prohibitive.
