Microsoft has revised the Azure Certifications. The idea of the new certification is that they should map to job roles and job duties. There are 3 levels from Foundation to Associate then to Expert.
Some of them have the transition exam from old Microsoft Azure Exams. But be careful that these transition exams will expire in June 2019. So be quick to take the exams if you plan to.
Here is the map of them.
Microsoft Certified Azure Fundamentals
This Certification requires you to sit and pass one exam (AZ-900 Microsoft Azure Fundamentals). This exam is listed as optional for all certification path, and it covers the core understanding of Azure. This exam is for both technical and non-technical people looking to validate their foundation knowledge of Microsoft Azure Services.
Microsoft Certified Azure Administrator Associate
This certification requires you to sit and pass two exams (AZ-100 Microsoft Azure Infrastructure and Deployment and AZ-101 Microsoft Azure Integration and Security). As this is a replacement for the old 70-533 exam if you have already passed it you can sit the transition exam (AZ-102 Microsoft Azure Administrator Certification Transition) but be quick as this exam is only available until June 2019.
Microsoft Certified Azure Developer Associate
This certification originally was two exams just like the AZ-100/101 however after reviewing feedback provided during the beta tests Microsoft removed some of the learning objectives and consolidated it in to one exam (AZ-203 Developing Solutions for Microsoft Azure). Whilst this is the replacement for the 70-532 certification there is no transition exam so anyone with that and looking to obtain the new Associate certification must take the whole exam again.
Microsoft Certified Azure Solution Architect Expert
This certification requires you to sit and pass two exams (AZ-300 Microsoft Azure Architect Technologies and AZ-301 Microsoft Azure Architect Design). As this is a replacement for the old 70-535 exam if you have already passed that you can sit the transition exam (AZ-302 Microsoft Azure Solutions Architect Certification Transition). As with the AZ-102 transition exam this one will also expire in June 2019.
Microsoft Certified Azure Dev-Ops Engineer Expert
To attain this certification you have to sit one additional exam on-top of either Associate certification – (AZ-400 Microsoft Azure DevOps Solutions)
This certification is a new domain for Microsoft, and is for those Azure Administrator Associates or Azure Developer Associates who wish to take their roles to the “expert” level. Not only does it focus on Microsoft Azure solutions but how certain OpenSource tools complement it. As this is a new domain there is no transition exam.
