[Cloud] OpenStack, Magnum, OpenShift


1. OpenStack

OpenStack an open-source cloud operating system that turns your server into cloud environments. In other words, it provides an open alternative to the top cloud providers. It is IaaS, and it can be used to automate resource allocation so customers can provision virtual resources like VPS, block storage, object storage among other things. 


2. Magnum

Magnum is an OpenStack API service that makes container orchestration engines, such as Docker Swarm, Kubernetes, and Mesos available, a first class resources in OpenStack. Magnum uses Heat to orchestrate an OS image, which contains Docker and Kubernetes and runs that image in either virtual machines or bare metal in a cluster configuration.


3. OpenShift

OpenShift is a platform as a service (PaaS) that leverages the core concepts of Kubernetes and packages them in a neat way for developers to deploy applications on the cloud. In short, it’s a modded Kubernetes, and accepts kubctl commands.

OpenShift Container Platform adds the following features to Docker & Kubernetes:
  • Source code management, builds, and deployments for developers
  • Managing and promoting images at scale as they flow through your system
  • Application management at scale
  • Team and user tracking for organizing a large developer organization
  • Networking infrastructure that supports the cluster

[Redis] Redis Cluster vs Redis Sentinel

1) In-Depth Guides to Redis Cluster and Sentinel For more in-depth explanation for Redis Cluster or Redis Sentinel, please read my other posts: Sentinel:  https://notafraidofwong.blogspot.com/2019/05/redis-redis-sentinel.html Cluster:  https://notafraidofwong.blogspot.com/2019/05/redis-redis-cluster.html 2) Deciding between Redis Sentinel and Redis Cluster Similarities : Both solutions provide high availability for your system. 2.1) Redis Cluster 2.1.1) Pros Shards data across multiple nodes Has replication support Has built-in failover of master 2.1.2) Cons Not every library supports it May not be as robust (yet) as Standalone Redis or Sentinel Setup and maintenance is more complicated 2.2) Redis Sentinel 2.2.1) Pros Automatically selects new master in case of failure Easy to setup, (seems) easy to maintain 2.2.2) Cons No data sharding; master might be overutilized. Another distributed system to maintain. 3) So how do I decide? In

[Unit Testing] Test Doubles (Stubs, Mocks....etc)

Image
In unit testing, isolation is key. The goal of unit testing is to test individual components, and not an entire system . The class/object/function you are testing is System Under Test (SUT) , and the other components of the system are Collaborators or Dependencies. Test Double  is a generic term for any kind of 'pretend' object used in place of a real object for testing purposes.  There are several types of Testing Doubles. We will start with: Fake Stub Mock Command Queries Mocks vs Stubs And then: Dummy Spies Spies vs Mocks I) Basic Testing Doubles a) Fake Fake are objects that have working implementations, but not same as production one. Usually they take some shortcut and have simplified version of production code. Note that Fake is a generic term - that can point to anything; usually mock and stubs. An example of this is an in-memory implementation of a database. This fake implementation will not access the actual database, but will u

[Node.js] Pending HTTP requests lead to unresponsive nodeJS

This is a recap conclusion to the potential problems of a NodeJS program I worked on previously. The program simulates thousands of clients navigating a website by sending thousands of http requests to a given API . The idea is to load test a particular API to make sure they can handle high traffic. Because we are simulating clients, it's important to keep track of the state of the simulated client as well. The problem with this program is it is buggy and becomes unresponsive from time to time (the only solution is to restart it). The problem was fixed by re-writing the entire program in Java, but it was regretful that I never had enough time to find the exact reason the nodeJS version of it failed. The following are potential causes I suspect: 1. Exceptions The NodeJS program was not written very neatly and stacked callbacks on top of callbacks on top of callbacks. This made it very difficult to keep track of exceptions and unexpected http responses are prone to happen. So
