DevOps - Introduction

What is DevOps?
It's a movement of people who think it's time for change in the IT industry - time to stop wasting money, time to start delivering great software, and building systems that scale and last. This movement is being called Devops.It’s born of the need to improve the IT service delivery agility, and this emphasizes the communication, collaboration and integration between software developers and IT operations. Rather than seeing these two groups as silos who pass things along but don’t really work together, DevOps recognizes the interdependence of the software development and IT operations and helps an organization produce software and IT services more rapidly with frequent iteration.

How does it help you?
The Devops movement is built around a group of people who believe that the application of a combination of appropriate technology and attitude can revolutionize the world of software development and delivery.


DevOps lifecycle

 The DevOps life cycle is a rapid release cycle with a strong feedback loop through:
  • Infrastructure Automation
  • Configuration Management
  • Deployment Automation
  • Infrastructure Monitoring
  • Log Management
  • Application and Performance Management

Why do DevOps?
Companies that incorporate DevOps practices get more done, plain and simple. They deploy code up to 30 times more frequently than their competition. And less than 50% of their deployments fail according to Puppet Labs 2013 State of DevOps survey.
The biggest shift in attitude in a DevOps environment is that there is one team composed of cross-functional team members including developers, QA, DBAs, business analysts, operations engineers and so forth.
The key benefits of a DevOps approach are :
  • Improved deploy frequency which can lead to faster time to market
  • Lower failure rate
  • Shortened lead time
  • Faster mean time to recovery
  • Faster release of apps with automation of integrated build, test and deployment process
  • Increase developer and operational efficiency by managing your infrastructure as code
  • Improve customer experience with immediate feedback loops and continuous improvement

Hash Functions

One way functions that transfer character inputs to compressed output value named as hash functions. The input can be infinite(arbitrary), but the output always has a finite(fixed) set of characters. This produces a fingerprint of the file/message/data source: Wikipedia You cannot reverse the function and get the input value in Hash functions. If you have the content, you can use the hash function to calculate the hash value, but the other way around is not possible. If you have the hash value and the function, you can’t use it to get the input text. Below are sample scenarios that hash functions may become useless. If the function is reversible, it’s not secure. Hash values can be exposed to the public. Hence we don’t want someone seeing the hash value. The values may not collision resistant. There may be use cases with two unique input values return the same hash value. Since digital certificates/Signatures using hash fun

CAP THEOREM

What’s C, A and P? Consistency is the easiest one. It roughly means that the clients get the same view of data. By saying that a system is consistent we often mean strong consistency, but it also can come in different flavors. Availability is a property saying that every request to a non-failing node will return a (meaningful) response. The response may not contain all data (so the harvest will not be 100%), but it should be useful for the client. Partition tolerance means that the system will continue working even if any number of messages sent between nodes is lost. This can be e.g. a network failure between two data centers, where nodes in each data center form a partition. Also note that a failure of any number of nodes forms a partition (it is not possible to distinguish between a network failure and a node failing and stopping to respond to messages). The basic statement of the CAP theorem is that, given the three properties of Consistency, Availability, and Pa

How you can manage throttle out errors in WSO2 API Manager

You might face the above-mentioned error if you have an application in Dialog Ideabiz platform.Let’s start from the beginning. Once you create an application on Ideabiz, you need to subscribe to the APIs you require. We use WSO2 API manager to manage the APIs . When admin approves your API subscriptions, he/she will assign a tier value for each API(5tps, 10 tps etc.). Also, they will assign a tier value for the application as well. Let’s assume you wanted to create an application by using SMS and Payment API. The team has assigned 5tps for each API and 10tps for your application. You use SMS API only to send SMS to the users and payment API to charge the users on daily basis. When considering each API, (as per above example) you should manage  5 transactions per second in the SMS API. Which means you can have 5 API calls per second. Let’s assume before you send the SMS, you want to charge Rs 1 from the user. Therefore you need to call payment API as well. Since the Pa
