What makes cloud the best!

Cloud is a perfect solution to small or medium businesses, the simple reason is the option to start up the business solutions can purchase services on a pay per usage or pay per time limit. So the investments are more precise when compared to the normal servers which need a months upfront payment or a yearly plan.

Think of it similar to game servers available at fatality servers today. You don’t need to buy large physical storage as servers for your needs. Moreover, it offers fascinating perks than regular servers.

The agility of cloud computes is regarded as the best, you can scale up your computing force on demand and this can be downgraded on request too. The best part of this is, the upgrade and downgrade does happen through a common front-end keeping things clean and under the customer control.

The interface of cloud system as mentioned earlier is very powerful and is capable of communicating with the services and making changes. The implementation for the interface is always in REST model, which classifies the services into active and the state of REST. So when the user is not carrying out any requests, there will be a cache area that serves in the request. Tools like SOAP extensions on PHP does help in creating custom functions for POST and GET requests which does help the interface work better.

The devices are setup remotely and most of the time data is off site and on a SANs or similar clusters. This ensures data to be secure and also provide the option for remotely monitoring updating the applications via any web enabled devices.

Another plus is the multi tenancy that the servers offer, so the whole office can work simultaneously on to the project and make or remove changes per request. In case of special campaigns or special offers, the system can be easily scaled up to meet the needs. Also the cloud computing offers better utilization and efficiency for each resource in use.

The SAN also helps you to have a reliable data and recovery options on the server data. But this doesn’t mean that the cloud is disaster resistant, there has been reports of data loss and issues on the cloud servers. But this should be comparatively smaller. Also note that the usage of cloud is just starting so we might learn about how this system works in real environment pretty soon.

The cloud is having a quicker span of maintenance time as you will still be served by different servers on the cloud and you will not be mostly having downtime through the process. Also there is a mention that cloud offers greater security, but this is again a flaw as per my view, with the data spread over and clients sharing the resources, there is always the chance of security flaw.


The above diagram defines how the cloud is being implemented. Starting with the client application which is the interface facing clients. The underlying hardware and software services reliant on the client module to work efficiently to deliver results.

This now leads to the application layer which is a service provided by cloud vendors, this is where the various

installations are done to the cloud to be used by end users. Normally the application layer is used to deploy Software as a service or SaaS. This helps users from stop installing a software which they might not need for a whole long period of time but might use it occasionally. The zoho or google office is one of the examples here. Usually SaaS is confused to be different entity. Usually the popular softwares are installed on the cloud to be made available as the service. The disadvantage of Saas is the lack of individual customizations, since the software is centrally installed clients will be receiving a copy to be used.

The Next layer is the platform layer, this is the basic OS or similar installations usefult for the deployment of software and frontend services. The cloud vendors provide this under the name Platform as a Service or PaaS, this offer helps in deploying applications without the cost of managing/buying hardware and network softwares. This is again a pay per use term, so the PaaS, helps to get past the barriers of purchasing/renting the servers on to datacenters.

The coming layer is the infrastructure layer, this is the basic NOC equipments and deployment options. The cloud vendors also provide this service as IaaS or infrastructure as a service, this helps you maintain level 3 data centers. Can place the servers and equipments over the interface provided and maintain the servers for the platforms to be installed. IaaS is widely and simply explained on the 3Tera application which has an amazing interface that just lets you drag and drop servers and network equipments.

The final layer is the base, the actual servers area which is spread across a cluster and also uses SAN to maintain the data and services available. The servers in use, is obviously multicore with huge RAM options to work with.
