What is Cloud Hosting?
Cloud computing is a subscription-based distribution model that provides scalability, fast delivery, and greater IT performance. It has removed numerous physical and financial obstacles to align IT needs with evolving business objectives. Cloud computing has become a significant force for corporate innovation in all sectors with a commitment to offering improved software, services and infrastructure easily and cheaply.
History & Evolution of Cloud Computing
The word “cloud computing” came into common use in the mid-2000s, but its roots can be traced back to a variety of computing business models starting in the 1960s that allowed consumers to purchase computing time on large mainframe computers instead of purchasing the hardware and software themselves.
The major vendors of hardware and software started using virtual machines in the 1970s as a way to provide autonomous, multiple devices, and operating systems on a host server. Through allowing multiple computing environments on a single physical device, this innovation in the shared mainframe paradigm allowed a communication and data revolution.
Telecommunications providers found they could deliver much cheaper, but with the same level of service as their old point-to-point data services, the latest private network connections. By the 1990s, telecommunications companies were creating surplus network bandwidth Virtual Private Network ( VPN) services that allowed companies to host their own software and data centers. During this time, the term “internet” came into common use because communication network diagrams reflect the handoff between the service provider and the cloud-based user.
Building on that early cloud foundation was a series of intermediate, but crucial, steps which integrated emerging technologies and business approaches that have become cloud computing as we use it today.
A network consisting of a centralized computer (hub) that is connected to less powerful computers or workstations (clients). The clients can use the hub to access data, content, and programs. As a model of security, it maintains compliance with policies.
Enables two computer systems to communicate with their counterpart (peer) directly without the need to connect to a central server. Unlike client/server approaches, peer networks share resources and become customers and suppliers.
A network, or grid, of connected computer devices that share resources to build a supercomputer that allows for large tasks, such as analyzing large data sets, to be divided among networked computers and performed in parallel to reduce computation time.
Introduced the idea of the computer resources pay-as-you-use. Consumers pay for the services they use, instead of a fixed rate of access. Computing services are offered as users require them, making this method more flexible and cost-effective.
The rise of the Internet and the World Wide Web, and their ability to connect large numbers of computers, was the catalyst that enabled full integration of these cloud-based technologies to create modern cloud computing.
How The Cloud Works & Key Technologies
Cloud computing isn’t going to affect how the company wants to provide information services, nor how the IT departments operate their organizations.
You can reap a number of benefits with cloud computing:
Infrastructure : Reduce spending on hardware by sharing storage and other cloud services, saving procurement cycles and cash.
Scalability: Improve the processing or storage of more cloud data with the ability to extend or reduce computing resources as required.
Automation: Reduce the need for additional personnel to manage software updates or compatibility of versions with various operating systems and databases.
Mobility:Access cloud information anywhere and anytime via web browsers to boost the efficiency of an increasingly mobile workforce.
Collaboration:Share cloud documents, data, and computing solutions to reduce platform accessibility-related governance issues.
Subscription:The transition to ongoing subscription licensing reduces the upfront spending on cloud computing and offers an opportunity to use operational budgets rather than capital spending.
A cloud provider provides the infrastructure for hardware and storage that companies can lease, usually at a monthly price. You may select your choices that may include a fixed offer or a mix of choices for storage, applications, and platform.
Public clouds deliver these advantages:
- No Download or Maintain apps.
- No equipment to purchase or to repair.
- Users will be able to manage and work with others.
- Users can have their own data uploaded.
Using a public cloud, as you might imagine, reduces the capital investment on software and equipment, which is a major benefit in an environment where technology can become practically obsolete overnight. But a big disadvantage is that in general (but not always) public clouds are seen as less secure than the second type of cloud computing environment: the private cloud.
When data protection is paramount, consider creating a private cloud. If your business is highly regulated or if data breaches open the door to reputational destruction, then you may want to think about building a private cloud. Private clouds can be built in your own data center, or in a highly protected third party data center you can pay for storage space inside.
You can see the obvious downside is the cost of building the infrastructure for cloud computing. The fixed costs of hardware, real estate and staffing can be substantial. Then there’s to consider the ongoing maintenance and overhead. Even if you choose to contract a private cloud provider, the cost may be considerably higher. But if you’re a company at the enterprise level where security and privacy are critical, then that’s an option you’ll want to explore.
If you need the best of both worlds-lower entry cost and greater protection-then consider a hybrid cloud option. Hybrid cloud computing is, as you probably guessed, a mix of both public and private cloud offerings. You can lock up your confidential data on private cloud servers and run applications and analytics using public cloud service providers.
If you are in a situation where you have multiple private providers, multiple public providers or several of both options, then it is far easier to handle those waypoints in the cloud. That is the safest choice for most organisations.
Cloud Computing Service Models
Software As a Service (SaaS)
Consider SaaS as the off-the-shelf alternative to get into cloud computing. It’s usually a standard set of offers that are available on a pay-as-you-go basis for immediate implementation. That helps you to quickly take advantage of new technologies. You can still use SaaS in your personal life without even considering it. If you are using a web-based email or calendar service, then you will use a SaaS form.
In addition to providing a pay-as-you-go delivery strategy, SaaS also ensures that you only pay for what you need, enabling you to scale up software and data storage resources as needed. When you have a more mobile workforce at one of your organizational imperatives, SaaS may be the solution. Service providers take care of allowing the cloud-based applications to run and control access and security on most forms of computers and mobile devices.
Platform as a Service (PaaS)
PaaS allows for the development and maintenance of custom cloud applications. It helps users to deploy their applications created or acquired using the programming languages, frameworks, and tools offered by the cloud host. The customer does not operate or monitor the underlying cloud infrastructure (networks, servers, operating systems and storage), but monitors over deployed applications, and possibly the settings for application hosting.
Using PaaS is best if you have a lot of developers working on the same project, or if you are using multiple sellers. It helps in many ways to simplify device development and fast deployment.
Infrastructure as a Service (IaaS)
But what if you want to just let someone else do it all? You need IaaS, instead. This is considered the most basic level of “as-as-as-service” at which consumers are equipped with network equipment and services. Those can include storage, networking, processing, and other tools for general computing. The IaaS user may run software from the cloud; access operating systems, applications, and frameworks; and perform general administrative functions, but the underlying infrastructure is not managed or controlled.
IaaS provides the cloud infrastructure which IT and operations usually access. IaaS provides SaaS and PaaS support for the cloud infrastructure. PaaS can provide SaaS production and support, but it isn’t required because SaaS can be provided on top of IaaS.
In conclusion, a cloud when setup correctly can indeed deliver all that you and your clients may ever need. By assessing fully what your current and future requirements are, we’ll be able to guide you to the correct informed decision.
