Gartner has just published the updated cloud IaaS scores for Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform (GCP)


In March 13, Gartner has published the new Cloud IaaS scores of AWS, Azure, and GCP, As mentioned by Gartner, "Compared to the previous assessments occurred mid-summer 2017, these new assessments show a steady growth in feature coverage by all three providers, with GCP leading the growth with an overall increment of 12 percent points. Azure follows with five additional percent points and AWS, which was the provider with the highest coverage also last year, marked an increment of four percent points. The figure below shows the details of the movements occurred within this update, broken down by required, preferred and optional criteria. It is interesting to note how some scores also went down (see Azure, required). When scores go down, it is not always due to providers removing features, but sometimes – like in this case – due to the modification of the applicability of the criteria’s scope".

Microsoft Exam 70-535 (Architecting Microsoft Azure Solutions) in a nutshell!


Many People are asking  and searching for the new Microsoft Exam 70-535: 

Architecting Microsoft Azure Solutions that is still in A version and B is still not released.

Few important points to know:

  • In its current version is coming in one only language which is English. 
  • The exam is coming is an adaptive exam that comes with couple of cases and each cases has some applied questions. Your answers to one case determine the next case you get.
  • Based on being an adaptive exam, means that once you leave one case you will not be able to return it back. This applies because the second case has been decided based on the answers of the previous case so, changing the answers of the first case may lead to changing the second case that you already have answered already which could create a lot of miss during the exam. that is why, this is already disabled and not possible initially.
  • The exam is based on seven pillars of knowledge. Here are they and some key points under each of them:
    • Design Azure Resource Manager (ARM) networking.

    • Secure Resources.

    • Design an application storage and data access strategy.

    • Design advanced applications.

    • Design Azure Web and Mobile Apps.

    • Design a management, monitoring, and business continuity strategy.

    • Architect an Azure Compute infrastructure.



Please note that The exam 70-534 includes main 6 topics. The 70-535 includes 7 topics. The main topics are different.
The 70-535 includes more features to study like CosmosDB, DMZ, WAF, AAD, Azure Key Vault, Event Grid and more.
in the The following posts I will speak about the content topics that you should be aware of in each of the seven pillar topics.
