Cloud computing is actually an internet based cloud computing in which shared resources, software, information and other devices on demand are provided readily to the computers. Customers using cloud computing service do not own physical infrastructure, instead they are able to avoid capital expenditure by renting usage from cloud computing India company.
Cloud engineering is the application of engineering disciplines to cloud computing. It brings a systematic approach to the high-level concerns of commercialisation, standardisation, and governance in conceiving, developing, operating and maintaining cloud computing systems. It is a multidisciplinary method encompassing contributions from diverse areas such as systems, software, web, performance, information, security, platform, risk, and quality engineering.
Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user’s data, software and computation.
Cloud computing relies on sharing of resources to achieve coherence and economies of scale similar to a utility (like the electricity grid) over a network. At the foundation of cloud computing is the broader concept of converged infrastructure and shared services.
In this most basic cloud service model, cloud providers offer computers, as physical or more often as virtual machines, and other resources. The virtual machines are run as guests by a hypervisor, such as Xen or KVM. Management of pools of hypervisors by the cloud operational support system leads to the ability to scale to support a large number of virtual machines. Other resources in IaaS clouds include images in a virtual machine image library, raw (block) and file-based storage, firewalls, load balancers, IP addresses, virtual local area networks (VLANs), and software bundles. For wide area connectivity, the Internet can be used or—in carrier clouds dedicated virtual private networks can be configured.
Cloud hosting is the latest form of hosting that has become extremely popular over the past few years. The main concept of cloud hosting is “Divide and Rule” – the resources required for maintaining your website are spread across more than one web server, and are rendered as per need basis. This greatly reduces chances of any downtimes in case of a server malfunction.
Another noteworthy aspect is that cloud hosting allows you to manage peak loads easily, without facing any bandwidth issues, since another server can provide the additional resources in such a case. Hence, your website doesn’t rely on just one server, and rather a cluster of servers that work together, termed as “the cloud”.
Future of Cloud Hosting:
Cloud hosting has come a long way, and several large enterprises have been using it for years together, but for the small business owners to be able to look at it, pricing will have to come down further. Having said so, the pricing has considerably come down over last 4-5years, and folks have learned the advantages of cloud hosting, which is compelling the mid-size organizations to make a move to the cloud arena.
Why and what cloud hosting is used?
There are many claimants to the concept of cloud computing but as users that is irrelevant to us. Cloud computing as the moniker suggests refers to computing power in an imaginary bubble which is called a cloud and allows users to access software, applications, data and what-have-you from a common location and this service is shared by multiple users within a secure or open environment.
Though the concept has been around for the last couple of decades under various names, the most recent one being SaaS (Software as a service), it is the recent increase in bandwidth availability and the need to share in order to be productive that has seen cloud computing become an acceptable concept. Some ways you may know it in your day-to-day life would be things like online file share services, Google Docs, mobile push and sync services and even email.
The two main components of cloud computing are the hardware and the software which are alighed to store, interact and deliver data. There are multiple applications that work in a cloud, including SaaS services, web based email and content distribution networks including file sharing apps.
Cloud computing has real benefits when it comes to data sharing and its these advantages which has led to its adaption in multiple organizations at a fairly rapid pace:
1) Bringing down computing costs in organizations. Most businesses are groaning under the costs of high-end hardware for their employees as apps become more and more resource hungry. Using a cloud to store apps which is accessible to users from a basic terminal brings in a control factor to these costs. Since cost cutting is a major concern these days, the concept of cloud computing is having its day under the sun.
2) Greater freedom for the cloud users as they can access data and applications from just about anywhere via multiple devices (like terminals, mobile, net books etc). Since the terminals can be quite basic, this helps bring down overall hardware costs as well.
3) Centralized and agile…might sound like a dream for some technocrats but it really is true. You can now use cloud computing to ensure that everyone is on the same page when it comes to computing standards, there is practically no down-time and just one implementation of a new application can result 100% implementation.
4) Security in cloud computing is much better than a scattered network and that is one of the reasons why clouds are working.
5) Clouds are also comparatively easy to manage and bring down the costs as well as headache of maintenance disparate servers. In fact network managers love cloud computing as it puts everything together in a very organized manner.
