Cloud computing

DLE helps set standards for consolidation of data centers and "transmission" projects.


Question about cloud computing

Here are some questions from customers who considers moving their IT systems and applications to the cloud.


- Can you tell me what the difference between SaaS, PaaS and IaaS is?

The differences between the three cloud service models are:

  • IaaS cloud services provides the ability to design and set up infrastructure for the cloud that can run within large parts of the spectrum of applications which are installed on-site.

  • PaaS cloud services include operating system software, middleware and support, without the need to design and set up IaaS infrastructure cloud.

  • SaaS cloud services deliver alternative cloud-based applications that are similar to those applications that are installed on-site (eg. Microsoft Office/Exchange to Office 365/Azure).


- What is the difference between public, private and hybrid cloud?

The differences between the three clouds are:

  • Public cloud is based on a standard cloud model in which a cloud service provider makes resources (eg. servers, applications and storage) are available to the public via the internet. Public cloud services may be free or offered on a "pay-per-use" model.

  • Hybrid cloud is an integrated cloud service model utilizing both private and public clouds to perform different functions within the same organization.

  • Private cloud computing is a term used to describe a cloud platform that is implemented within a corporate firewall and mainly within the organization's IT department.



- How will I be able to see whether the move to the cloud will work well for us?

Based on business factors that drive your transition to the cloud, it should be very easy to determine what the key success factors are:

  • Savings in CapEx over the next 1-5 years.

  • Is the utilization of the servers improved?

  • Cancellation of maintenance contracts for IT.

  • Faster product launches.

  • Reduction in the number of calls to the maintenance support department.

  • Scalability

  • Flexibility

  • And many more…


- How do I choose the best applications for moving to the cloud?

This question can only be answered by analyzing your current IT systems and applications, to first identify those with low resource usage and low storage requirements. The other applications that have higher resource usage and/or large storage needs will require a more in-depth analysis, before moving them over to the cloud.



- Are there any limitations to what can be moved to the cloud?

The only limitations on the amount of local IT infrastructure and applications that can be transferred to the cloud is your budget limit for OpEx operating costs, which will be substantially less than your current CapEx budget.



- When will I see a return on my investment in using the cloud?

You will see a return on your investment within the first year, with the biggest return being seen after five years.

- Will my IT users see a difference in application performance, like slower or faster response time?

Yes, they will. Depending on which solution is implemented, they should see a noticeable increase in application response times, and customers will also be able to see an improvement. There should be no visible reduction in response times for applications.
