What is the cloud?

Simply put, cloud is a set of resources available to you, to get your job done. As a starting point, lets see how our day to day activities are linked to the cloud. Most of us use Google photos to uploads and save pictures, or Dropbox to share files. Well all of these services are present on the cloud and your data is being stored on cloud.

An extension of the basic cloud is the concept of Cloud Computing which is a shared set of resources like servers, operating systems, storage devices, applications can be accessed on-demand over the internet for any computational needs. Still confused? Let’s look at some examples for a better understanding. For instance, if you have a website, you must be hosting it on Bluehost or HostGator etc, they provide you with an operating system to run 24/7 for your website to be accessible, storage for saving your web pages and media files and other resources.

One of the biggest concerns you might face when your data resides on infrastructure that you don’t own, is security. There are various security measure you can take to protect your data, and most cloud platforms avail these facilities. If you have highly confidential data moving in and out the cloud, you can always use encryption keys — provided by cloud platform or your own to protect the data. Also, certain industries need to follow security rules for protecting their data, like HIPAA for healthcare industry, PCI compliance in case you are handling any online transaction. All of these are can be taken care of on the cloud.

You also don’t have to hire a large IT team to take care of infrastructure set up or taking care of the security, all of this will be handled within the cloud. You can immediately see a huge difference in your investments when you take these points into account.

Well it does cost some money to avail premium support and the cloud platform support team will make recommendations for handling your IT to best fit your business needs. But you could justify this cost if it is going to save you millions!



Most cloud service providers take responsibility to assure that your services hosted on the cloud are fault tolerant. You don’t have to worry about losing connectivity to your resources over the internet, they are guaranteed to have up time of ~99.95%. You can also choose to make it highly available by distributing the load on multiple servers too.

Structural changes happen all the time, so you need to give some thought around how flexible your platform is to handle those changes without any major refactors. So when you start building your infrastructure, you can choose resources based on your business needs like the OS you want to set up, the network capabilities, the storage size etc. When your business demands changes you can alter the resources with ease — like changing the type and size of server you are using. All changes are in place with just a couple of clicks.


Backup and Recovery

No matter the size of your organization, you always need to take precautions and be prepared for disaster recovery. A lot of organizations still rely on automated processes or even worse, they have individuals taking daily backup of their data files.

When your data is on the cloud, you have the luxury of just setting up rules and leaving the rest to be handled by the cloud platform. Your backups and data recovery will be taken care of without having to wait for IT teams to take action in case of emergencies. Also, the time for recovery is much shorter when you compare with on-premise recovery processes.


With growing businesses, there is a need to add on resources to your stack for coping with larger workloads. Let’s consider any ecommerce website, during the holiday season, they expect a lot of traffic to their website so they can scale up and add resources to handle the additional traffic. Once the holiday season is through, they scale down so they can save $$ by shutting down resources when they are not being used. Scalability applies to bandwidth as well, you can tell the services you use, the number of requests/users it can handle.
