Cloudfoundry: Open Source Platform as a Service A platform used for running applications and services. The purpose of cloudfoundry is to change the way apps and services are deployed and run by reducing the cycle time of development to deployment. Cloud Foundry directly takes benefits of cloud-based resources such that apps running...
In my previous blog post, I wrote about Cost Optimizations for the various AWS resources. The script consisted of six methods and the overall time required for the script to execute was roughly about 15-20 mins. While the script is running, it used to slow down my system. Also, there was a time consumption due to many reasons like...
Zabbix is an Open source distributed monitoring tool. It allows us to monitor integrity and health of the server, network traffic, and applications. Zabbix uses a notification mechanism that allows users to configure e-mail based alerts for virtually any event. Components Used in Zabbix are as follows: Zabbix Server :...
As we know AWS provides a good edge in terms of cost over the on-premises data center or in a co-location environment with its On Demand and Reserved pricing. As it is rightly said "Reducing the overall cost is a high priority" and it is true for any organization whether big or small. By using AWS we can lower the IT costs, compute...
AWS S3 is a Simple Storage Service provided by Amazon that can store any amount of data, at any time, from anywhere on the web. It is one of the most heavily used AWS Service. It is not just used as a storage service, it is also used for hosting websites with static content. It is easily integrated with many other AWS services and tools. ...
Autoscaling is a service in AWS, which is used to launch or terminate an instance based on user-defined policies, health checks, and schedules. There are several ways to configure an auto-scaling group in AWS, here we are focusing on implementing it in python using AWS python module boto. Before Creating an Autoscaling Group ...
The demo aims at running rails application behind Nginx using Passenger. Nginx is a high performance webserver. Passenger is a free web server/application server with support for Rails, Python, Node.js. Passenger is highly stable and fast already service over 350,000 websites. 1.

Locust is open source and distributed load testing tool , intend to load test websites. A fundamental feature of locust is that you can describe all your test case in python code. This lightweight, distributed and scalable framework helps us to find out how many concurrent users a system can handle by writing test case scenarios in...
We have been using ELK as a centralized logs management system. ELK stands for Elasticsearch, Logstash, and Kibana. Each of the three services is running inside its own docker container in one docker-network (say elk-net) on a single server. A separate block storage device is mapped from the host into Elasticsearch container (named es)...
Logstash is a service that accepts logs from a variety of systems, processes it and allows us to index it in Elasticsearch etc which can be visualised using Kibana. Our DevOps engineers have been using Logstash S3 plugin which simply puts all data in a S3 bucket location. Since we have configured files to be created in every hour on...
In the recent past, software has seen a revolution of sorts. The emergence of Docker and the containerization paradigm has questioned the basis of some of the software delivery principles. The result? People are opting for things unheard of some two years back. What’s more, they are now using them successfully to deliver software faster...
DevOps and Cloud is a combination one cannot resist. It not only makes the development process more efficient but leads to business success as well. The advantages are many; on-ground indications reveal that DevOps is a more productive way to develop software, plus it means better quality resulting code and faster delivery time. With...
