Cloud Computing And CISSP – All Questions Answered
Cloud computing is the trend in the world of Information Technology. Organizations no longer need to have dedicated resources both in terms of money and people to manage their IT needs in-house. You will rarely see an IT team today which manages IT resources like Servers, CPU, RAM, bandwidth or disk space internally. All these things are now handled through cloud computing services.
What is Cloud Computing?
Simply put, Cloud Computing is a network of servers maintained in data centers that are overseen by third party service providers. The servers do not have to be in the same place as your organization or your workplace. They can be anywhere. The biggest benefit is the seamless access despite the geographic spread. You can read up on the detailed benefits and the types of service models in one of our earlier blog posts - Cloud Computing – The Global SWhattandard Of Internet Business.
How Does Cloud Computing Help?
Cloud Computing helps many ways. It helps both organizations and individuals. For an organization, the first and foremost benefit is cost advantage. In addition, organizations can now focus on utilizing IT personnel for achieving business goals and not just as a maintenance team. The most important benefit for an organization probably is the speed at which they can bounce back even in extreme calamities, as the servers stay safe.
For an individual, the benefits are huge too. You can work from anywhere, even from home while still staying connected to your office network. Most of the apps that you use on a daily basis (food delivery, cab booking, ticket booking etc.,) are a product of cloud computing.
In a nutshell, Cloud Computing is hugely helpful. It is scalable, secure, cost effective, aids business continuity, helps working from anywhere. It can’t get any better than this!
What Kind of Service Models are Available?
There are majorly three types of service models that are prevalent in Cloud Computing – Infrastructure as a Service (IaaS), Platform as a Service (PaaS) and Software as a Service (Saas).
In an Infrastructure as a Service (Iaas) model, a client can choose the infrastructure they need and pay only for those specific services. This model works for all scale of businesses.
In a Platform as a Service (PaaS) model, a software stack is offered by the cloud providers. This model works well for widely spread organizations that are into extensive web applications like an e-commerce company.
In a Software as a Service (SaaS) model, software is delivered online. Examples are all kinds of social networking sites and web based email services.
