  7. Telemetry • Hot-path • Run Scope for exception handling within logic apps (similar to a try/catch) • All exceptions are not created equal; may need to enumerate through exceptions before posting • Single logic app concept to move exceptions into an Event Hub (not the same used by Logic Apps) • Azure Functions consume exceptions from Event Hub for both App Insights and internal Ticket management system • Warm-path • OOB Logic App infrastructure plus Integration Account • Event Hub and OMS • OMS drives non-flow business exceptions

  8. ALM and Dev-ops IST PST Enterprise Commerce / Volume Licensing Supply Chain / Core Integration Service CFE Common Backlog (shared and triaged across regions) Feature Branches Feature Branches Feature Branches sprint Sprint teams live here: iterating through tasks and user stories until features are ready or sprint ends. What’s passing tests makes it to release Pull request into develop ‘develop’ CI / CD DRI’s work here: Executing PR’s into ‘release’ and managing the deployment across primary/secondary regions. Issues found here can be dealt with by DRI following Git best practices for this scenario Pull request into release ‘release’ Pre-production (PPE) DRI’s work here: Executing PR’s into ‘master’ and managing the deployment across primary/secondary regions. Issues found here can be dealt with by DRI following Git best practices for this scenario Pull request into master ‘master’ Production

  9. ALM and Dev-ops • Git for source control. • Each code check-in goes thru pull request (code review), at least 2 approvals required and enforced thru branch policies • Code is compiled – gated check in build • Policies for security or governance enforcement (e.g. scan for potential security risks or ensure the person checking in code is supposed to be) • Azure DevOps (formerly known as Visual Studio Online (VSO)) for build and release management. • Two builds • Gated check in – code check in and performs compilation of the code executes unit tests • Continuous Integration build – used to deploy/release, compiles the code, runs the unit tests and creates a build structure to be consumed by release/deployment. • Release • One release pipeline for each environment • Each release pipeline consists of steps to perform various tasks to complete tasks in a given environment and run functional tests • Branching Strategy • Following a basic Git practice of using a ‘develop’, ‘release’, and ‘master’ branch • Deployments into CI, PPE (Pre-Production), and Production • Deploy core services components on a sprint cadence • Unit test / functional test • Unit test what can be unit tested • Functional test for things like Logic Apps, APIM Policies, and any other non-unit testable capability that makes up the integration service • In general • Agile != ‘No Process’ • Dev-ops != ‘No Governance’

  10. Security and Governance • IP Whitelist to further secure logic apps (Migration to ISE) • Managed Identities for AAD auth between logic apps (HTTP Actions/Triggers). Remove SAS token from URL • Things to consider in a hybrid environment • Access Management – who has access to my system when considering PaaS and on-premises resources (e.g. BizTalk) • Release Management – Separation of duties between developers and release management in production • Privacy – How to handle highly confidential data or personal data (e.g. cosmosdb, table/blob storage, Azure SQL • Cost Optimization – Once you begin to figure this PaaS thing out, how do you corral the cost

  11. AIS Migration Story Milestones Achieved Metadata driven Architecture Migration Accelerators • Metadata Creation • Schemas Json • Maps Json • End Point • Flow Context • Partner Flow Context • Schema Provisioning • Partner – Agreement json creation • Maps to XSLT conversion • Metadata creation • AB Testing

  12. Enterprise Integration Disaster Recovery • Scheduled Sync Solution’s • Runtime Sync • LogicApps scheduled to run every 3 mins to update secondary region Integration account to make them sync and vice versa post DR. • AS2 Synchronization (MIC Algorithm) • X12 Synchronization (Control Numbers Sync) • EDIFACT Synchronization (Control Numbers Sync) • Artifacts Sync • Integration Account Artifacts sync scheduled to run every 1 hour to secondary region and vice versa if needed. • Schemas • Maps • Certificates • Partners • Agreements • Assembly • Batch Configurations • RosettaNet PIP • Pre/Post DR Scripts Execution • Bump Interchange Control Numbers in secondary region and vice versa post DR. • Flip Azure Traffic Manager(ATM) routing from Primary to secondary APIM and vice versa post DR. • Disable/Enable LogicApps. • Lookup Azure Storage Table sync.

  13. Appendix • Open-source Accelerator Tools, Demos and scripts available at Github https://aka.ms/Integrate2019 • Write to us for any integration queries: btsmigrationtool@microsoft.com

  14. Recap – B2B Approach • Use one Integration Account and set of logic apps across multiple Businesses and Trading Partners (Partner info, Agreements, Document Types, Schemas, Maps, Batch Configurations) • Flow concept static but type can be overridden based on message (e.g. different logic apps that process X12 or EDIFACT messages) • Metadata used to populate runtime properties specific to a TP or a LOB (currently stored in a CosmosDB and accessed via Azure Function with caching) • A ‘Routing Slip’ can override the URL of next logic app to load (can be overridden using APIM Policy)

  16. Recap – B2B Approach Secondary Logic Apps Service Lines (Business Units) • Gateway provides an Active/Active store and forward mechanism for B2B type traffic. Trading Partners post messages to endpoint which round robins between the two regions. • There are two deployed installations of B2B Service. However, only one is active and any time. • At deployment time, artifacts are deployed to both regions. This includes all static data including Logic Apps, Functions, Metadata • During runtime, there are properties that are updated in the Enterprise connectors that must be replicated across both regions for business continuity. In the passive region, there is a set of logic apps responsible for listening to events in primary region and updating the appropriate Integration Account Artifacts • EHC provides secure connectivity to on-premises resources. B2B Service uses corpnet BTS 2016 servers • BTS 2016 provides pass-thru connectivity to existing LOB Applications over a wide range of technologies • BTS 2016 provides the necessary capabilities to send and receive messages from LOB Applications Corpnet BTS2016 APIM EHC Gateway TP Replication for Busn.

  18. Composable Architecture • Patterns and Composable Services • Composable Flows for integrations • Leverage existing patterns or compose a new one • Microservices should be autonomous • Refactor to net-new, don’t change an existing pattern or service

  19. Composable Architecture • Routing Slip Pattern • APIM, API, and Policies to expose and describe pattern • Context to describe the flow specific parameters that allows for multiple scenarios to flow through one pattern • Generic ARM Templates to describe concepts that may need implementation specific properties at deployment time (e.g. FileAdapter, SFTP, Message publishing and subscribing patterns) • AdapterRouter concept for endpoint implementation details
