Here is something we all have witnessed at some point of time. Everybody keeps talking of some term, it becomes a buzz-word in no time & then it becomes so hugely popular that you won’t dare to ask what-the-heck-it-actually-means? Right 😕

Ok,  so here is one sincere attempt to unravel the hazy world of Cloud..!  

We’ve come a long way from that famous quote “ 640K ought to be enough for anybody”! With the ICT convergence, 3G (& now 4G) network & the humongous BIG social media apps, DATA is growing faster and faster.   No wonder, if given the choice to move one workload to the cloud, most choose storage & which has given rise to Cloud computing model of IaaS – Infrastructure as a Service, which basically offers  bundled services of Compute, Storage, Network & Security requirements. Many organizations are moving their ERP applications to Cloud either at the time of hardware refresh/upgrade or are directly hosting the applications on Cloud right from the inception of business. By doing this, not only they move away from Capex to Opex (Capital expenses to Operating expenses), but also enjoy the scalability of Cloud (can add/reduce storage/compute/network bandwidth as per the need) within an agreed SLA-framework! While Amazon is a global leader as IaaS provider, ICT players like Sify Technologies (India’s first SSAE-16 Cloud certified provider) in India have helped many organizations in moving their ERP applications (& especially SAP) to Cloud seamlessly.

PaaS (Platform as a Service) – Here cloud providers deliver a computing platform, typically including operating system, programming language execution environment, database, and web server. Application developers can develop and run their software solutions on a cloud platform without the cost and complexity of buying and managing the underlying hardware and software layers. With some PaaS providers like Microsoft Azure and Google App Engine, the underlying computer and storage resources scale automatically to match application demand so that the cloud user does not have to allocate resources manually.

SaaS  – In Software as a Service (which is also called as ‘On-demand’ software) model, cloud providers install and operate application software in the cloud and cloud users access the software from cloud clients. This eliminates the need to install and run the application on the cloud user’s own computers, which simplifies maintenance and support. The pricing model for SaaS applications is typically a monthly or yearly flat fee per user so price is scalable and adjustable if users are added or removed at any point.

  1. Saleforce.com, Ariba, & Success-factors (latter two are from SAP stable) are some of the hugely popular applications used by enterprises all over the world to manage their sales/purchase/HR processes dynamically.

SaaS allows a business the potential to reduce IT operational costs by outsourcing hardware and software maintenance and support to the cloud provider. This enables the business to reallocate IT operations costs away from hardware/software spending and personnel expenses, towards meeting other business goals. In addition, with applications hosted centrally, updates can be released without the need for users to install new software.

Depending on the deployment options, Cloud is classified under Public, Private & Hybrid Cloud, which vary due to security considerations.  As the world embraces Cloud, Cloud players are adding more and more stringent layers of security through software/hardware firewall & Managed Security services (including data encryption technology) .

Last word .. Cloud is not vaporware, it is there to stay and …only to grow bigger and BIGGER by the day!

So, when is your organization moving onto Cloud nine 😕
