Cloud computing infrastructure

The cloud infrastructure refers to the back end components of the cloud architecture such as servers, storage devices, networking elements and virtualisation software. Thus cloud infrastructure is a mix of both hardware and software components. It is an essential part of all three cloud-computing models.
Business organisations use the cloud infrastructure to host their applications. To use the cloud infrastructure of the service provider, clients make use of pay-as-you-go model in which they pay for only the services used by them. This is a very cost-efficient means of using the required infrastructure and can be done in an hourly, weekly or monthly basis.
Most cloud service providers who are into Infrastructure services rely on virtual machine technology (or Virtualisation) to deliver servers and run client applications. Virtual servers act really well like physical servers delivering a certain number of microprocessor (CPU) cycles, memory access and network bandwidth to customers. These virtual servers are containers having specific physical resources (or) a specific capacity of a large physical hardware. The concept of virtual servers enabled the application developers to have a new perspective towards application programming.
Consider an example of a programmer creating software that requires several different tasks to be performed in parallel. He needs to write the complete code to execute all the tasks and in addition, he would go ahead and create a separate module to handle different threads of execution (or) connect and automate all the different tasks. The developer can create and attach an application that uses a cloud service to the appropriate service and allow the application itself to scale the program execution. Therefore, an application that might take long time for a single server to accomplish can be scaled in the cloud to many servers at once for a short period of time to accomplish the task at faster rate at similar or lower price.
Post 2010, some readymade code pieces (or) libraries have been made available by Infrastructure service providers that helps application programmers to connect them with their application and execute required additional tasks without spending much time in re-coding every time.

Now that we have discussed in brief about cloud infrastructure, let us now look at few leading players in the market. 

Brief about Amazon Web Services

Amazon Web Services (AWS) offers reliable and extensive cloud application and infrastructure services for all types of organisations, with over 10 years of experience in supporting enterprises with affordable cloud services, AWS cloud has grown into a leader in cloud storage and management of various critical business processes.

Key things to know about AWS

•AWS is the pioneer in the cloud computing race and managed to retain its top position through the years.
•Recent price cuts have allured more start-ups as well as government agencies towards the AWS cloud.
•Amazon offers three types of computing instances: on-demand, reserved and spot. All three options come with different pricing structures.
•Amazon’s cloud offering for Big data analytics is called Amazon Elastic Map Reduce.


Microsoft Azure and BizSpark
Microsoft is yet another strong contender in the cloud technology space. It offers a unified set of tools, automation capabilities and innovative approaches to networking and storage. Microsoft the industry’s best hybrid cloud solutions while keeping the compliance and security costs to the minimum.
Microsoft Azure
The enterprise-grade cloud computing platform from Microsoft is called Azure and it supports a wide selection of tools, languages, frameworks, databases and devices. Statistics reveals that 57% of the Fortune 500 companies from various industry sectors entrust their data and applications with Azure. The easy-to-implement and low cost hybrid cloud solution offered by Microsoft Azure is a good fit for organisations of all types and sizes.
Microsoft BizSpark
Start-ups that are looking to leverage the power of cloud must turn to Microsoft for its BizSpark program. This three-year program includes tailor-made cloud solutions for the newbies in the block. 


Google Cloud Platform
The Google Cloud Platform allows users to build applications and store data on Google’s highly reliable and scalable infrastructure. The innovation power of Google is world renowned and by leveraging its cloud platform, developers can gain quicker access to its technological innovations.
Key things to know about Google Cloud Platform
•Google’s network can be defined by its thousands of miles of fibre optic cables connected through cutting-edge Andromeda networking. The consistency and speed of such a network is unparalleled.
•Data is 100% secure through backup storage across multiple locations.
•The per-minute billing system allows users to handle traffic spikes with the most cost-effective solutions.
•The BigQuery and Google Cloud Dataflow tools offer full support to big data solutions.
The fact that Google Cloud Platform works on the same infrastructure that supports the mammoth tasks of Google itself is indeed the greatest advantage. Users can be assured of high availability, lesser costs and low latency

The Seven-Step Model of Migration

Irrespective of the migration approach adopted, the Seven-step Model of Cloud Migration creates a more rational point of view towards the migration process and offers the ability to imbibe several best practices throughout the journey Step 1: Assess Cloud migration assessments are conducted to understand the complexities in the migration process at the code, design and architectural levels. The investment and the recurring costs are also evaluated along with gauging the tools, test cases, functionalities and other features related to the configuration. Step 2: Isolate The applications to be migrated to the cloud from the internal data center are freed of dependencies pertaining to the environment and the existing system. This step cuts a clearer picture about the complexity of the migration process. Step 3: Map Most organisations hold a detailed mapping of their environment with all the systems and applications. This information can be used to distinguish between the ...

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...
