St Louis CMG Modernizing and Managing Enterprise Applications in the API Economy Chris Walker – Offering Manager, IBM z Systems Monitoring January 2017

© 2017 IBM Corporation Abstract Businesses are realizing that there is considerable value gained from exposing existing core applications as APIs for developers to rapidly build cloud and mobile apps. This session will explain how hybrid applications that span the enterprise from distributed to the mainframe can benefit from an end to end application performance management view, including a focus on z/OS Connect, Java workloads, as well as traditional workloads such as CICS and IMS on z Systems. The Digital Economy is forcing business to transform

5 What is the API Economy?

The API economy is an enabler for turning a business or organization into a platform. Gartner, Christy Pettey June 2016 1

In the API economy, application programming interfaces (APIs) act as the digital glue that links services, applications and systems. This allows businesses to make the most of their data to create compelling customer experiences and open new revenue channels. IBM 1 http://www.gartner.com/smarterwithgartner/welcome-to-the-api-economy/ 6 What is meant by “API”?

An API is a set of commands, functions, protocols, and objects that programmers can use to create software or interact with an external system. It provides developers with standard commands for performing common operations so they do not have to write the code from scratch. TechTerms.com

7 Where are APIs? Everywhere!

8 The Strategy is Simple…

Unleash Enterprise Investments to Disrupt Competitors

To Develop Innovative Exposed as Apps APIs

…With Hybrid Applications

9 z Systems is the ideal System of Record for Hybrid apps

CRM HR Clients have built and tuned core

DB ERP applications on the mainframe using Systems of CICS, IMS, DB2 over many years Record No other platform provides the reliability, availability and performance

14 What scares the z team about managing hybrid apps?

Controlling Costs! Skills and Agility! Managing Risks!

 Too much expert time is  Our app dev team  How do I know who is wasted in crit-sit war knows Java not COBOL! calling our APIs? rooms!  We can’t install new app  How can I predict /  Additional workload will versions every week! protect the workload? drive up our MIPS!  “They” don’t include  How do I know if the  Training developers is “us” in strategy or user experience is expensive! architecture! impacted by my host performance?

15 The Lifecycle of a Hybrid Application

Application Operational Operational Expose APIs Consume APIs Understanding Monitoring Analytics

16 Application Unlock the value of existing assets Understanding

• Understand the structure of your business critical applications across languages and environments • Challenge for mainframe clients is knowing/understanding the assets already available • Decide what has value to be exposed as an API • Look to reduce risk and time and increase quality of changes through tooling that can identify those dependencies between assets • Result is ability to create or refactor assets to be consumed as API’s Create Microservices and APIs Expose APIs

• From the identified assets, develop microservices that perform a single task to interact with the System of Record • Example: “getCustomerByID” • These microservices can be later integrated, if needed, to form exposable APIs to end users. • Use tooling to create the mapping from existing application endpoints into a RESTful interface • Example: mapping a COBOL copybook into a JSON structure Surely, our clients can do this today?! Expose APIs

CTG or CICS SOAP/JSON Webservices CICS IMS Mobile Feature Pack IMS DB2 JSON DB2 Broker MQ JAX RS WAS Yes, but … Expose APIs

Multiple endpoints for developers to call/maintain access to

CTG or CICS SOAP/JSON Webservices CICS IMS Mobile Feature Pack IMS DB2 JSON DB2 Broker MQ JAX RS WAS

These are typically not RESTful!!! Completely different configuration and management  A transformational gateway is required Expose APIs

Discovery using OpenAPI CICS (aka Swagger)

IMS RESTful APIs available from one endpoint DB2

MQ With sophisticated mapping of true RESTful APIs to WAS existing mainframe services and data Managing APIs Consume APIs The challenge: • Who is accessing the APIs? • Is it public? Who has keys? • How can socialize (advertise) the APIs? • What is the quality of service? • Do we have traffic policy enforcement (throttling)? • Can we meter any chargebacks? API management and orchestration Consume APIs

• How do you combine multiple CICS backend services in a single IMS useful API? DB2 MQ

WAS ?

Other Enterprise servers Operational End-to-End monitoring of hybrid applications Monitoring

• Application driven monitoring changes the focus of what is meant by acceptable performance • Need to leverage existing investments in z monitoring and management into overall view of hybrid application • Consistency of data between LOB Application Owner and z Operations teams

Faster problem isolation with visibility into mainframe components

24 Typical hybrid app scenario with a mainframe today

It’s probably the The business Uh-oh! It’s a DB mainframe. application isn’t DB2, MQ and lock on distributed performing like it CICS on z/OS slowing down the should. Where’s that are all performing response time infrastructure contact? ? fine

25 Evolution of personas that need and use monitoring data

Application Owner z/OS Subject Matter Expert

26 Operational Minimize outages with Analytics Analytics

• Real-time monitoring provides ability to manage effects on performance however there is also a need to observe and react to a bigger picture • The impact of API usage draws in metrics from various sources: • Traditional monitoring resource data • Real-time feeds of SMF data and log data • Client (mobile) connection information • Unstructured data • Creates a feedback loop that identifies the bottlenecks, usage levels and value of the APIs and services

27 Example Scenario: BreadBox Grocery

• Global footprint. • Family run retail business. • Enterprise operations - 50 states • Optimize and Innovate in IT • Started by 2 brothers in • 3 data centers in the US • New Services Online fast to Ohio. • 500 distribution centers reach new clients. • Rapid Growth via • 45000 trailers & 4000 drivers • Leverage Social & mobile for commitment to clients and • 12000 stores better client engagement Innovation in IT. • Growth through acquisitions. • Maintain Industry Leadership

31 Miki – Application Owner

• Responsible for one or more applications. Most often employee of the business unit

• Needs to ensure that applications are running and meeting SLAS.

• Looking ahead at trending and capacity planning.

Miki • Needs to understand when problems happens if Application Owner those are application or dependent component related (Middleware, Infrastructure)

32 Scenario • Miki is the Application Owner for the Virtual Shopping List at Bread Box Groceries

• Miki uses Application Performance Management to monitor the overall responsiveness of the application using Synthetic Transactions

• Miki has been notified that the response time for the application is slow

Miki • Miki logs onto the APM UI and notices that there Application Owner are warning events in the application dashboard indicating that the CICS transaction used by the VSL are slow

• Miki contacts the CICS SME to let him know that the slow CICS transaction times are impacting her application 33 Virtual Shopping List Architecture
