Abstract
Modern applications are highly modular, increasingly cloud-based and rely on
microservices for connectivity. Managing performance in these highly dynamic
environments can be challenging but doesn't have to be. Join this session to
understand how to use CA APM Extensions for AWS, Docker and other common
cloud technologies.

Applications are Architected Differently
Microservices
(Agile, loosely-coupled, independent, continuous delivery)
Monolithic
(Tightly-coupled dependent, waterfall, change intolerant)

Microservices: Monitoring Scale & Complexity
Microservices Architecture is an emerging technique which promises to deliver
flexibility and scalability to the development and deployment of service based
applications

Monitoring Must Scale with New Architecture
Microservices
architecture with
each element of
functionality in a
separate service….
Scales by distributing services across
servers, replicating as needed
MICROSERVICE CONSIDERATIONS
§ Testing across multiple services
§ Release co-ordination
§ Many moving parts / multiple instances
§ Many new data stores – SQL, NoSQL
§ Network latency, messaging, emergent
behaviors
§ Complexity!

Containers: Monitoring Complexity & Scale
Containers include the application and all of its dependencies, but share the
kernel with other containers. Docker containers are lightweight, run on any
computer, on any infrastructure, in any cloud and are great for microservices

Cloud – Monitoring Scale
Cloud computing is about access to a pool of computing resources (servers,
storage, networks, services etc) that can be rapidly provisioned and made
available with minimal overhead – NIST

E.P.I.C. APM
Smart agent
• Collect what you need when you need it
Monitoring at scale
• Monitor @scale and clustering
Ease of administration
• Get control with CA APM Command Center
Simply visualize large complex data
• CA APM home page and Assisted Triage help quickly
identify and diagnose problems that matter
Elegance @Scale

• Node.js agents are fully supported and provide transaction correlation,
deep dive root cause analysis, browser agent for end user analytics
• https://www.npmjs.com/package/ca-apm-probe

Continuous Integration/Deployment: Monitoring for Resiliency &
Change
Continuous integration is a process in which all development work is integrated as
early as possible and the resulting artifacts are automatically created and tested.
This process should identify errors as very early in the process.
