Broad Approaches to Migrating

The first step towards building a strong cloud strategy is planning the migration of the existing applications to the cloud. This task requires much effort, the right skill set and planning. There are three common approaches to migrate the on-premises applications to the cloud. They are:

1. Lift and Shift

As the name suggests, the Lift and Shift approach involves the exact replication of the in-house applications in the cloud. There is no change made to the code or the design of applications. It involves much lesser time, cost and complexity when compared to other methods. However, applications migrated to the cloud using this technique do not take complete advantage of the native cloud capabilities. Storage infrastructure and disaster recovery are common applications migrated using this approach.

2. Refactoring

Refactoring refers to changes made in the structure of the source code of the application in order to make it more efficient. The code is modified such that it becomes more scalable and reusable without changing the functions of the application. In other words, this approach to cloud migration adheres to the concept of get-something-working-now-and-perfect-it-later.

3. Modernization

The modernization application approach to cloud computing redesigns the application from ground up, thus making it completely flexible for the cloud environment. While superficially this procedure may seem expensive or complex, the new applications provide maximized benefits through decreasing the costs substantially.

Cloud Computing architecture

Cloud computing architecture refers to all components and sub-components that together form the structure of the cloud computing system. This architecture can be divided into three parts for better understanding – front end, back end and middleware. Each part of the cloud architecture has its own set of functionalities and protocols that work together to deliver on-demand services to user-facing hardware as well as software. In general, the architecture is evolved out of large distributed network applications over the last two decades. Hence it supports any system where resources can be pooled and partitioned as required. The general cloud architecture is capable of running multiple software applications running on multiple virtual hardware in multiple locations to efficiently render on-demand services to the users. The users could be using these software applications from their desktop or laptop or mobile or tablets. Usually, whatever the user is looking at – through t...

connection oriented

connection-oriented:- connection-oriented  describes a means of transmitting data in which the devices at the end points use a preliminary  protocol  to establish an end-to-end connection before any data is sent. Connection-oriented protocol service is sometimes called a "reliable" network service, because it guarantees that data will arrive in the proper sequence. Transmission Control Protocol ( TCP ) is a connection-oriented protocol. For connection-oriented communications, each end point must be able to transmit so that it can communicate. The alternative to connection-oriented transmission is the  connection-less  approach, in which data is sent from one end point to another without prior arrangement. Connection-less protocols are usually described as  stateless  because the end points have no protocol-defined way to remember where they are in a "conversation" of message exchanges. Because they can keep track of a conversation, connection-or...

What is technical analysis?

 Technical Analysis (also abbreviated as TA) is a popular technique that allows you to do just that. It not only helps you develop a point of view on a particular stock or index but also helps you define the trade keeping in mind the entry, exit and risk perspective.  Like all research techniques, Technical Analysis also comes with its own attributes, some of which can be highly complex. However, technology makes it easy to understand. Technical Analysis is a research technique to identify trading opportunities in market based on the actions of market participants. The actions of market participants can be visualized by means of a stock chart. Over time, patterns are formed within these charts and each pattern conveys a certain message. The job of a technical analyst is to identify these patterns and develop a point of view. Like any research technique, technical analysis stands on a bunch of assumptions. As a practitioner of technical analysis, you need to trade the markets k...
