Tightly coupled modules, which cannot operate independently.
  6. 6. Monolith Vs Microservices

I/we allow Agile testing alliance to use the content for social media marketing, publishing it on ATA Blog or ATA social medial channels(Provided due credit is given to me/us) Micro services advantages – Easy Deployment – Reliable – Available – Scalable – Selective – Manageable
  8. 8. Micro services Design… • Divide functionally ,focused towards the way its needs to be consumed • Map and design the services to be independent • Have Separate Data Stores , which is denormalized
  9. 9. Micro services Design … • Define REST endpoints, with required flexibility only • Make Sure there are SPOFs • Establish a service registration and discovery infrastructure (Easier Loadbalancing)
  10. 10. Micro services Design • Containerize the services • Docker with Kuberneties • Make Sure there are SPOFs • Establish a service registration and discovery infrastructure

I/we allow Agile testing alliance to use the content for social media marketing, publishing it on ATA Blog or ATA social medial channels(Provided due credit is given to me/us) Micro services and DevOps • DevOps and micro services work better when applied together • Containerised Services – Simple to maintain DevOps env, – Each once of them can be treated equally • With a single script handling all of them • Easier Adoption of CI and CD principles – Micro services + DevOps = Agility

I/we allow Agile testing alliance to use the content for social media marketing, publishing it on ATA Blog or ATA social medial channels(Provided due credit is given to me/us) Micro services and DevOps • Not only deployment and maintenance it also simplifies the delivery and Integration of the product easier • Micro services can increase teams velocity, together with the CI and CD practices • They complement the cloud-based application architecture, by supporting event driven programming and auto-scale scenarios.

I/we allow Agile testing alliance to use the content for social media marketing, publishing it on ATA Blog or ATA social medial channels(Provided due credit is given to me/us) Handling a sudden surge • Micro services can be spawned on demand, – utilizing a sophisticated DevOps infrastructure in place and – brought down once the spike in gone, and – hence utilizing the resources in best way on a Cloud platform . • This makes sure that only the required services are multiplied – and only the required minimum infrastructure is consumed (and hence billed on a Cloud Platform). • Containerization removes the dependency on the target platform, – and reinforces the system of any failure due to 3rd party mismatches , and hence more robust.
