Wherever we look we see that companies of all sizes and scale are shifting big parts of the organization from ownership to access. Whether it’s cloud computing, office space, accounting or any other part that is not considered as their core business.

Looking back at 10 years ago, who would have believed that cloud computing will serve most of the infrastructural needs of most of the tech-based companies. Not so long ago, if you would have asked a CTO of an insurance company to place their code and data on someone else’s servers, he would have probably smiled and explained politely that this is out of the question.

But today, people ask themselves why should they invest so much time and energy doing something they are not specialized at and most probably don’t like to do, and furthermore why at all to own such a function in the organization with all its overheads. Now… the question is where to draw the line.

Cloud computing means

Cloud computing means the delivery of on-request computing resources over the Internet. Cloud computing service provided by many companies, the most popular are AWS, Azure, Google Cloud, Microsoft etc. Office space is also a great example of this movement, great companies like WeWork offer a perfect solution for companies of all sizes so that they can do what they love without the need to think about cleaning the office, Wi-Fi or if there is enough milk in the kitchen. You can easily upload to cloud photos, documents, even your computer or laptop backup. For example, Netflix uses cloud computing services to run its video streaming service. Cloud computing has become the default option for many mobile and desktop apps.

Types of cloud computing:

  • Software as a Service (SaaS) — direct access of user to cloud without installation additional app or program;
  • Platform as a Service (PaaS) — tools and software for developers, that are necessary to build the apps;
  • Infrastructure as a Service (IaaS) — virtual infrastructure that includes hardware parts, like processor speed, physical or virtual servers, storage, networking etc.;
  • Network as a Service (Naas) — provided with network connectivity services, such as VPN and bandwidth on demand;

Also, clouds differ due to the type of using:

  • Public Сloud — no visibility and control over where the computing infrastructure is hosted.
  • Private Cloud — the information totally dedicated to your company, secured by firewall and fully controlled by the company.
  • Hybrid Cloud — the mix of public and private cloud, so you can use private part for important data and public for general info storage.

Clouds have a more complicated structure in comparison with dedicated servers, as it is not a simple virtualization type. Cloud computing refers to a service that results from that manipulation. Cloud solutions can be expensive as it requires a higher level of security protection.

The main advantages of using cloud computing:

  • Stability & elasticity.
  • Standardized interference.
  • Storage capacity.
  • Access from any device and part of the world at any time.
  • Easy way to share the data.
  • Automatic updates.
  • Back-up and disaster recovery.
  • Flexible payment.


  • security and privacy risks;
  • vulnerability to attack;
  • downline and Internet reliance;
  • less control level;
  • complicated and expensive data transfer.

Cloud infrastructure is really popular in the IT industry, as it makes software development easier. Some analysts predict that half of global enterprises will cloud computing by 2021.

To sum up, cloud computing helps to manage data, allows to get quick access. Looking to improve data exchange in your company — try cloud services, the Smartexe experts will help you with the cloud integration and configuration.
