Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Fault Tolerance in Distributed Systems: Strategies and Case Studies
Failure Detection and Recovery It’s not enough to have backup systems. It’s also crucial to detect failures quickly. Modern systems employ monitoring tools and rely on distributed coordination systems such as Zookeeper or etcd to identify faults in real-time: once detected, recovery mechanisms are triggered to restore the service.

Analysing Github Stars - Extracting and analyzing data from Github using Apache NiFi®, Apache Kafka® and Apache Druid®
You can install Kafka from https://kafka.apache.org/quickstart. Because Druid and Kafka both use Apache Zookeeper, I opted to use the Zookeeper deployment that comes with Druid, so didn’t start it with Kafka. Once running, I created two topics for me to post the data into, and for Druid to ingest from:

How to choose the right API Gateway
Next, review deployment complexity such as DB-less versus database-backed deployments. For example, Kong does require running Cassandra or Postgres. Apigee requires Cassandra, Zookeeper, and Postgres to run, while other solutions like Express Gateway and Tyk only require Redis. Apache APISIX uses etcd as its data store, it stores and manages routing-related and plugin-related configurations in etcd in the Data Plane.

ElasticJob 3.0.2 is released including failover optimization, scheduling stability, and Java 19 compatibility
ElasticJob achieves distributed coordination through ZooKeeper. In practical scenarios, users may start multiple jobs in the same project simultaneously, all of which use the same Apache Curator client. There are certain risks due to the nature of ZooKeeper and the callback method of Curator in a single event thread.

Avoiding DevOps tool hell
The Hashicorp corporation has made a huge impact in providing valuable tools and platforms in the cloud ecosystem. The advantage of using the tools they provide, such as Terraform, Vault, and Packer, is that they all have the same language, Hashicorp Configuration Language (HCL). This means you can easily pick up any of these tools by learning HCL, which is similar to JSON. This approach can be useful when choosing tools to learn or use for a project.

How to Set Up an Azure Kubernetes Service Cluster with Terraform
Terraform is an open-source infrastructure as a code tool. It is designed by HashiCorp and written in Go Programming Language. Terraform is used to automate the creation of DevOps infrastructure and tasks. Terraform provisions and configures your DevOps infrastructure. It spins up new servers, creates load balancers, and node groups, and performs network configurations. Terraform is mostly applied to provision resources on cloud providers like AWS, Google Cloud, and Microsoft Azure. It can automate and provision infrastructure on any cloud platform. We will use Terraform to set up an Azure Kubernetes Service Cluster that has all the necessary cloud resources.

Automating and managing your ConfigCat resources with Terraform
It can be time-consuming to create and manage the infrastructure that drives your software applications as they grow and become larger. Also, what about ongoing updates and releases of new features? Luckily, there is a solution to this problem in the form of a tool designed by Hashicorp called Terraform. This allows us to define our infrastructure in a central configuration file without having to create it on every provider platform we use.

Policy-as-code is recommended for managing cloud and SaaS services
HashiCorp Sentinel: Sentinel is a PAC tool developed by HashiCorp that can be used in tools such as Terraform, Vault, and Nomad. Sentinel supports writing rules in programming languages such as HCL to automate the enforcement of security and compliance policies.

Terraform 101: The What, the Why, and the How
Terraform is an infrastructure as code tool (IAC) created by HashiCorp that lets you automate cloud and on-prem resources. It uses configuration files written in HashiCorp Configuration Language (HCL) to declare resources (infrastructure objects) and define dependencies between them. To put it simply, this tool allows you to write a few configuration files and build a whole system’s architecture on the cloud by running a couple of commands. I found this to be a more efficient alternative to clicking through a console to create resources manually.

To Infinity and Beyond: Our Nomad Migration is complete!
It was clear back in 2021 that Lob needed to consolidate how we run code and none of our current tools were up to the task; it wasn’t a matter of if Lob would upgrade to something new, but when. The Platform team kicked off a research project to find Lob’s next service platform. Forever ago (back in 2019) we investigated migrating to Kubernetes, a popular but notoriously difficult-to-manage tool for this sort of thing, but that project fizzled out for many reasons, forcing us to consider something else. We chose Nomad which offers a comparable feature set to Kubernetes in a much more streamlined package. Nomad is developed by HashiCorp, a leader in the DevOps space, and is used by companies like Pandora, Cloudflare, Internet Archive, and Roblox.

GKE with Consul Service Mesh
If however, you have an application service that needs support for 2+ ports, because you know, Kubernetes supports this, I would recommend avoiding Consul Connect, as it is not functional to meet minimum requirements for a service mesh. Perhaps someday, when Hashicorp prioritizes basic functionality and usability in future version, this product can be considered.

Feedback? This is a logo I made for my friends gaming brand. It’s a simple H letter logo
Looks a lot like Hashicorp (a technology company), maybe too similar, and not particularly evocative IMO.

The Best Terraform Feature Yet?
AWS VPC is a simple example. This feature really shines when building reusable infrastructure-as-code for Network Firewall or even Network ACLs. Anything that simplifies something and reduces or eliminates any hacks required to reach a logical outcome is super valuable. Great work finally driving this one home HashiCorp.
