There’s never been more options -- or more confusion -- about which technologies to use when connecting systems? When is BizTalk Server the right choice? Should I still use WCF? Is the Windows Azure Service Bus ready for production scenarios? In this session, we’ll first do an overview of each core technology in the integration portfolio. Then we’ll review a simple decision framework for down-selecting your choices. Finally, we’ll have an interactive discussion (and demonstration) of real-life scenarios and which technology is the right fit.

  • Previous book (cover) <br /> Technology count: WCF, WF, AppFabric, BizTalk, ESB, SSIS, SSSB, Sync Framework, Azure SB Relay, StreamInsight <br /> Technology count TODAY: WCF, WF, AppFabric, BizTalk, ESB, SSIS, SSSB, Sync Framework, Azure SB relay, Azure SB Brokered, Azure VMs, Azure Notification Hubs, BizTalk Services, StreamInsight <br /> LET’S TALK THROUGH SOME TRENDS THAT EMERGED SINCE THIS BOOK
  • Source: http://www.flickr.com/photos/davenielsen/5718247676/sizes/l/ <br /> <br /> Cloud computing <br /> Change to the traditional computing paradigm <br /> Host matters less; elastic, on-demand <br /> Accepted part of an organization’s app portfolio <br /> New types of applications and scenarios <br /> Widely distributed <br /> Mix of hosting providers <br /> Different integration scenarios <br /> Cloud to cloud, ground to cloud, cloud to ground
  • Source: http://www.flickr.com/photos/mattandbeccasteudelwedding/9067696311/sizes/l/ <br /> <br /> Micro Services <br /> Something championed by ThoughtWorks a while back, and now something Netflix (and others) do a lot of <br /> Mini applications/services <br /> No heavy, complex services <br /> Very specific services that are easy to consume and weave together <br /> Think of cloud providers who have distinct services for provisioning services, autoscale, etc
  • Source: http://www.flickr.com/photos/24752578@N02/5589897831/sizes/l/ <br /> <br /> Lightweight Integration <br /> It’s not just about a powerful, centralized integration server <br /> That’s of course always been the case, but new attention paid to simplified messaging <br /> Something between a basic queue and a full blown ESB <br /> New tools, new way to connect lightweight services together
  • Source: http://www.flickr.com/photos/anekoho/9638930676/sizes/h/ <br /> <br /> NoSQL endpoints <br /> New types of endpoints, often outside your direct control <br /> Relational databases are less important now than ever <br /> Still a place for them, but major companies are finding they don’t need them <br /> We’ve replaced our SQL backend with one <br /> To the integrator, this adds new scenarios
  • Source: http://www.flickr.com/photos/peternijenhuis/6959653638/sizes/h/ <br /> <br /> Automation <br /> DevOps and the cultural movement to unprecedented synergy between Dev and Ops teams <br /> Automated builds, continuous integration, continuous deployment <br /> Possible to get rid of snowflake servers, and move to immutable servers
  • Source: http://www.flickr.com/photos/suckamc/5907306188/sizes/l/ <br /> <br /> We want to be at a place where we have the simplest toolset possible, but one that meets our needs <br /> This continued expansion of available integration services is logical, when considering these trends <br /> There are more and more tools for specific scenarios (micro-integration services), and fewer monolithic tools that serve EVERY purpose
  • How do we get there? <br /> Walk through a decision framework <br /> Talk through the available technologies <br /> Apply these principles <br />
  • What’s a decision framework? <br /> Way to analyze a situation and identify the right fit <br /> There cannot be a massive decision matrix that drops the correct solution in your lap <br /> Instead, there are multiple dimensions to consider, and those may be unique to each organization and situation <br /> Steps <br /> First, let’s discuss the sources that describe our situation <br /> Then, we’ll talk about the 4 dimensions to discuss
  • Input into a decision … <br /> Functional requirements <br /> What is the application supposed to do? <br /> Business requirements
  • Input into a decision … <br /> Non functional requirements <br /> Describe what the system itself needs to do to support the functional requirements <br /> security, availability, maintainability, compliance, exception handling, etc <br /> You can argue if these are actually functional requirements, and in some cases they are
  • Input into a decision … <br /> Derived requirements <br /> Ones that aren’t explicit stated, but can be derived from what’s needed <br /> Based on a functional requirement to provide a certain type of data, I might derive a requirement to persist data in a warehouse for long range analytics
  • Input into a decision … <br /> Organization direction/strategy <br /> This is the least transferrable! <br /> What are the company goals, investments? <br /> These are often fixed, and non-negotiable <br /> <br /> <br /> NOW, LET’S TALK ABOUT THE DECISION CRITERIA ITSELF
  • Solution design – design patterns required <br /> Data volumes, data set size, guaranteed delivery, data sources/destinations, latency, sync/async, data processing (workflow, quality operations), SSO, failure handling <br /> MODERN UPDATES … (reliability of endpoint, location of endpoint, constraints imposed by source/destination, circuit breakers) <br />
  • Solution development – what it takes to build the solution <br /> Developer availability, learning curve, developer setup, IDE and tool integration, support system, source control integration, automated builds <br /> MODERN UPDATES … (works in cloud, web-based IDEs, continuous integration/delivery support) <br /> <br />
  • Solution operations – what it takes to maintain the solution <br /> Event logging, tuning ability, handle bursts and failures, backup/restore routines, support tools, versioning capabilities, scriptability <br /> MODERN UPDATES … (immutable runtimes, rapid releases/rollbacks, works in distributed fashion) <br /> <br />
  • Organizational considerations – enterprise standards and org direction <br /> Long term solution, vendor support, uses existing software investment, limited budget impact, build vs buy compatibility, risk tolerance, speed to market <br /> MODERN UPDATES … (OSS, commodity skill sets, easy/no upgrade) <br /> <br />

Dynamics CRM Online or Salesforce.com
  • Options … <br /> Use messaging and use BizTalk to send messages to vendor endpoints <br /> PRO: Good tracking, chance for enrichment before sending out; guaranteed delivery <br /> CON: hard to quickly change endpoints; puts responsibility on internal team to manage/scale; <br /> Use messaging and use BizTalk to send to Topics, local DB, and notification Hubs <br /> Use messaging and send loans directly to SB topics (and internal DB) from WF <br /> PRO <br /> CON <br /> Send loans to SB topic and one listener is internal DB <br /> PRO: Simple, offload responsibility for delivery <br /> CON: No coordination; chance of race condition; no notification for vendors of new messages <br /> Send loans to SB topic, one listener is internal DB, and also use Notification Hubs for alerting <br /> Provide REST-ful query API (exposed via SB) on loan DB and use notification hubs to send messages to providers to query and provide their best offer <br /> PRO: Simple; no replication; easy to onboard new vendors; offload availability to 3rd party; durable; <br /> CON: Not event based; need to chain together way to notify vendors; no orchestration or tracking; limited visibility into vendor processing <br />
  • Let’s consider the option that leverages the Service Bus for all this <br /> Send a message to Notification Hubs so very easy to broadcast info and push alerts <br /> Use Topics for scalable, durable messaging <br /> Subscribe ourselves to update internal systems
