Anyone who needs an access to a particular piece of software can be subscribe as a user, whether it is one or two people or every thousands of employees in a corporation. SaaS is compatible with all internet enabled devices. Many important tasks like accounting, sales, invoicing and planning all can be performed using SaaS. PaaS Platform as a Service Platform as a service, is referred as PaaS, it provides a platform and environment to allow developers to build applications and services.

This service is hosted in the cloud and accessed by the users via internet. To understand in a simple terms, let compare this with painting a picture, where you are provided with paint colors, different paint brushes and paper by your school teacher and you just have to draw a beautiful picture using those tools. Software developers, web developers and business can benefit from PaaS.

It provides platform to support application development. It includes software support and management services, storage, networking, deploying, testing, collaborating, hosting and maintaining applications.

It provides computing infrastructure like virtual server space, network connections, bandwidth, load balancers and IP addresses. The pool of hardware resource is extracted from multiple servers and networks usually distributed across numerous data centers. This provides redundancy and reliability to IaaS. For small scale businesses who are looking for cutting cost on IT infrastructure, IaaS is one of the solutions. Annually a lot of money is spent in maintenance and buying new components like hard-drives, network connections, external storage device etc.

What is Cloud Computing Architecture? Cloud computing comprises of two components front end and back end. Front end consist client part of cloud computing system. It comprise of interfaces and applications that are required to access the cloud computing platform. While back end refers to the cloud itself, it comprises of the resources that are required for cloud computing services.

It consists of virtual machines, servers, data storage, security mechanism etc. It is under providers control. Cloud computing distributes the file system that spreads over multiple hard disks and machines. Data is never stored in one place only and in case one unit fails the other will take over automatically.

The user disk space is allocated on the distributed file system, while another important component is algorithm for resource allocation. Cloud computing is a strong distributed environment and it heavily depends upon strong algorithm. Virtualization is a partitioning of single physical server into multiple logical servers.

Once the physical server is divided, each logical server behaves like a physical server and can run an operating system and applications independently. They are fast, cost-effective and less time consuming. For software developers and testers virtualization comes very handy, as it allows developer to write code that runs in many different environments and more importantly to test that code.

Data Center Architecture Overview

Storage Virtualization: It is the pooling of physical storage from multiple network storage devices into what appears to be a single storage device that is managed from a central console.

Storage virtualization is commonly used in storage area networks SANs. Server Virtualization: Server virtualization is the masking of server resources like processors, RAM, operating system etc, from server users. The intention of server virtualization is to increase the resource sharing and reduce the burden and complexity of computation from users.

Virtualization is the key to unlock the Cloud system, what makes virtualization so important for the cloud is that it decouples the software from the hardware. Usually hard disk has a lot more space than memory. Although virtual disks are slower than real memory, if managed properly the substitution works perfectly. Likewise, there is software which can imitate an entire computer, which means 1 computer can perform the functions equals to 20 computers.

Grid Computing Vs Cloud Computing When we switch on the fan or any electric device, we are less concern about the power supply from where it comes and how it is generated. The power supply or electricity that we receives at our home travels through a chain of network, which includes power stations, transformers, power lines and transmission stations.

Grid Computing is a middle ware to co-ordinate disparate IT resources across a network, allowing them to function as whole. It is more often used in scientific research and in universities for educational purpose.

If all of that energy-devouring equipment is sitting there in the building with you, power and cooling are your problem. It would sure be nice to unload some of those issues on someone else, so you can focus more of your attention on using technology, not just feeding it.

How could your organisation not come out ahead by replacing a collection of individual physical servers with virtual servers? Truth is, the return on investment varies greatly with the size of the data centre, and smaller installations may have a harder time passing the break-even point. But those concepts can make your IT staff a bit nervous about their own job security. For many organisations, the move toward the next-generation data centre includes the challenge of hanging onto the team members you need for a successful future.

Driving IT Transformation The roadblocks outlined above are among the many reasons most organisations are making the move toward consuming IT as a service. Doing so unlocks a wide range of problem-solving ideas, and paves the way to harnessing game-changing abilities that have never before been available. What you need is there, ondemand, whenever you need it. As you reap the benefits of Infrastructure as a Service, Platform as a Service, and Storage as a Service, your organisation will gain significant flexibility, simplicity, and savings through the Software as a Service model.

The consumption model, needless to say, brings with it an entirely different budgeting situation. Things that were once capital expenditures increasingly become operational expenditures. That frequently means less spending overall, usually means lower upfront expense, and generally brings spending accountability closer to the end users and aligns it more tightly with specific business ventures. Abstraction further reduces complexities and simplifies the process for users.

The fact of the matter is, under this 17 model, additional or upgraded technology is more readily accessible than it would be if you had to go out and buy it, navigating the capex process along the way. This newer approach also would fail if security was lacking.

The good news is that your data can be just as secure using a pay-as-you-consume approach as it would be if it sat there in a physical server right next to your desk. The IT operations model In the transformed picture, the IT operations model is quite a bit different from what IT staffers and customers have known for so long.

For example, provisioning has been a labour-intensive pursuit, but it can largely be automated in the latest operational model, as can many other operations. Noncore functions can be outsourced, for lower costs and often greater efficiency. The fun stuff! By unloading a lot of the mundane infrastructure responsibility, the IT department has more freedom to work closely with those on the business side, innovating new ways to truly meet the needs of the organisation.

Because too many trends are making the current model obsolete. There are new types of transactional usage every day, involving customers and employees alike who have never had reason to tap so deeply into data centre information in the past. These new users are accessing data by way of new devices that go far beyond their computers.

Their phones are making connections, their tablets, their smart TVs, the onboard computers and GPS systems in their cars, the security and control systems watching over their homes and businesses, their wearable fitness devices, their electric meters, even their refrigerators.

As you imagine all of the tasks being accomplished through this growing list of devices, you realise how many more applications and workloads are joining the mix.

And as all of that change unfolds, it becomes clear that the list of locations tapping into any given data centre is growing exponentially.

Users need access at absolutely any time, from virtually anywhere in the world. The more data that gets aggregated from all of these users and devices, the more ways that data can be crunched and analysed to gain astonishing new insights into health, human behaviour, customer purchasing trends, natural phenomena, economic activity, and virtually any subject of interest.

It takes a lot of next-generation data centre elements to really unlock the power and value of Big Data. A New Kind of Data Centre The next-generation data centre is one that has broken free of the traditional definitions and boundaries involving facilities, computing, storage, and the data centre network.

It embraces the cloud in a big way to enjoy the benefits of IT as a Service. It recognises that the enterprise network must be a fundamental part of all data centre decisions, because the network is what unlocks all of the possibilities by connecting all of the parts, from the onsite data facilities to the cloud.

Is the next-generation data centre on your premises, in a co-located operation, or in the cloud?

What is Cloud Computing?

Rethinking the Facility A next-generation approach to data centre design involves a careful examination of facilities, including the operations there, the opportunities for virtualisation, and the benefits of converged infrastructure. It requires a meticulous examination of the computing resources that will be needed and what form they will take, the amount and location of storage, and the network that allows the various parts to interact with one another.

Internet and enterprise network considerations will also help in the planning of how and where workloads will be processed, and the benefits of software-defined networking will play a key role. A big part of the planning will involve evaluating how the cloud fits in — when to use it, how much to rely upon cloud services, and which kinds of workloads are ideal for migrating to the cloud. The goal is to examine all applications, from legacy applications to those born and bred in the cloud, determine the mix of those applications that will align best with business needs, evaluate where those apps will run most effectively, and move three-tier applications smoothly between the data centre and the cloud as required.

Co-location is an essential part of many data centre designs. That can both achieve more 24 cost-effective networking and help address latency issues between your data centre and the cloud.

A Security Blanket Enveloping all of the various aspects of the next-generation data centre is an overarching focus on security. The risks to corporate data and customer information are greater than ever before, which is obvious not just to IT specialists but to practically everyone who reads the news.

Security risks are greater for a lot of reasons. To begin with, the bad guys out there are more sophisticated, and they have better resources than ever for carrying out their operations. But the challenge is also greater for a lot of the same reasons driving the move toward next-generation data centres in the first place.

For example, the complexities introduced by all of the new devices that need data centre access also create new pathways for security breaches. The need to achieve greater global accessibility also opens doors to hackers in faraway places. Unstructured data that can be so valuable for Big Data analysis also poses security threats of its own.

Cloud services can be just as secure as onsite resources. Even so, when data centre elements are shared between onsite, co-located, and cloud resources, it can be trickier for IT security personnel to keep their eyes on the full picture.

That makes it essential to work with reputable providers and partners staffed with the very best security expertise. The same way any journey begins … with a single step. This chapter offers thoughts on how to begin the journey. Get an outside partner to help plan a transition and set up a matrix of small, digestible efforts that can yield early successes. As elements of the data centre move toward cloud services and cloud-based tools, that can pave the way for a move from the waterfall development model to the agile approach.

Rather than a sequential approach from concept and design through testing and production, the agile approach emphasises early delivery and continuous improvement. The agile approach encourages healthy risk taking through smaller, incremental changes. Just one more benefit of moving in the direction of the cloud. Mapping Out the Data Centre Development Model A next-generation data centre can simultaneously deliver powerful new capabilities, achieve cost savings, and make life easier for end users and IT staffers alike.

Inputs into the development model include assessments of enterprise mobility and next-generation desktop technologies that users will employ to gain access. The development model moves forward into assessments of data centre architecture and service architecture, to begin to paint a picture of what should happen where.

An exploration of facilities includes the storage, computing, security, and network platforms, with an eye toward virtualisation wherever it makes sense. Alongside that is the consideration of cloud services that will handle some of the storage and workloads. Vitally important is the evaluation of the connections — the Internet and enterprise network that link all of the pieces.

And underpinning it all is a focus on the security architecture that ensures the safe functioning of all parts of the data centre. Figure explains in detail. Here are ten parting thoughts. The network is the real key to the kingdom.
