Editor's Notes
- #6 Analogy: You have a building, you want to allow people in and out of your building. Doors are used to allow people to enter or exit your building. People must conform to the way in which a door allows entry. It may be a door you push, you pull, or perhaps slide but you as the building owner are instructing visitors on how to get in or out of your building
- #7 Expand on why Spec Driven Development is important: Code First Design First Self documenting
- #8 These are the building blocks of an API Economy ISVs – build Software solutions that expose API endpoints to enable organization to exchange Data New Channels – new opportunities emerge as a result of the API. For example many startups rely upon other APIs to build their business. For example an Auto Insurance company who wants to introduce self service quoting. Marketing and Customer Relationships – For many organzations there is a renewed focus on Customer Relationship Management. With Social Media platforms being used by hundreds of millions of people world wide these people now have a platform and organizations are paying attention to Customer Sentiment. This is all being driven through APIs. API Security – While there are no bullet proof solutions when it comes to Security, there are some common approaches used then securing APIs such as Oauth or identity federation such as Active Directory or Social Identity Internal Agility – Ultimately introducing APIs to your organization should provide a layer of agility for your business. In the upcoming demonstration, I should be able to prove this out.
- #9 Programmable Web is tracking 13 174 public APIs on their website programmableweb.com . It is safe to assume there are millions more hidden inside the enterprise.
- #13 Let’s pretend the doors in the previous slide are the doors to a night club. Some night clubs will not have a doorman or a bouncer. The clubs that do chose to implement doormen, do so in order to maintain order. The owner of the club wants to protect its business or assets. The bouncer is there for: Authentication and Authorization: Authenticate and Authorize people by looking at their ID, ensuring they are of legal age, ensure they are not on the “Do not enter list” Policy Enforcement - The Doormen is also there to ensure that people have a good time. If there is an unruly consumer the doorman there is to restore order and deal with those types of customers Analytics - The doorman provides analytic services. Buildings often times have restrictions on the number of people who can be in the club at a particular place. The bouncer uses his “clicker” to count the number or people entering or exiting. Customer Engagement Promote the club – the doorman may hand out promotional materials to entice customers to come into the club
- #14 Authentication and Authorization – Checking someone’s ID Policy Enforcement Provide a good experience – Noisy neighbor. Or those people that are enjoying themselves perhaps too much and need to be put in order Analytics – You want to understand where your customers are coming from, what products they are interested which helps you drive future investment. Developer Engagement – how do you onboard new developers? Making an API simple will ease adoption. Tell story of USA Today MLB Salaries API discovery.
- #15 Not sure if you have ever seen a dog show on TV but it is pretty amazing to see dogs turn on a dime. An API Management Platform is there to provide similar capabilities for you business. By having an agility layer you can then pivot your business when a new business opportunity emerges without having to spend a lot of time in long development cycles.
- #16 You can think of API development in terms of a life cycle We can project existing services as APIs or build our own Publish our APIs to developers and partners in anticipation of integration Monitor our APIs from both a business and operational perspectives Engage new developers and communities to further expand our APIs reach
- #17 Talk about a very competitive landscape A lot of acquisitions in this space: Microsoft bought Apiphany Intel bought Mashery CA Technologies acquired Layer 7 In addition to these acquisitions other vendors such as IBM, Tibco, SOA Software(akana) and MuleSoft have offerings. SAP signed partnership with Apigee
- #18 Let’s start at the backend where we may have existing or new services that need to be built. These services may be on-premise or may also be in the cloud. Once you have your backend stabilized you then can begin the Admin process where you apply different policies based upon business need. These policies can include JSON-XML conversion, rate limiting, security Once the API has been published you can now connect Apps that will make requests to the Proxy and the proxy in turn will communicate with the backend services. Since all traffic is moving through the Proxy, this is where our analytics are available to us. Once we have everything configured and are satisfied with the experience, we can make our API discoverable through a Developer portal where developers can sign up for your API, get an application key and then use a developer console in a variety of languages.
- #19 Let’s double click and take a closer look at the architecture There are a lot of features that exist within an API Management platform. You would not want to build this on your own.
- #21 Last time we caught up with Vince Vaughn, he was an intern at a start up company in Silicon Valley. Based upon his success at this startup he is now a savvy IT Manager at an Insurance company on the East Coast.
- #22 Insurance Business – offer services to new audiences We now have a director from the business who wants to provide a mobile experience for his customers and create new revenue channels through partnerships.
- #23 Like may Line of Business owners, he wants rapid results. Vince Vaughn on the other hand has seen how long it takes to get anything done in IT and knows he cannot make that 6 week deadline as there are just too many concerns that him and his team will need to deal with. Like many IT Managers when faced with adversity, Vince polishes up his resume and hopes his team come up with a Hail Mary in order to keep his job.
- #24 After cautioning the Business Director that 6 weeks was not likely to happen, the Business Director became very upset. He also has a grandson who is a Minecraft champion so surely this cannot be that difficult. If he can set up a MineCraft server in the cloud then surely these guys can allow customers to get quotes over their cellphones.
- #25 Vince then reaches out to his new hot shot architect. Unfortunately he is stumped and is not sure how to solve the problem in such a short timeframe. He then reaches out to Mike Stephenson who seems to have all the answers these days. Mike suggests looking into API Management.
- #26 After hearing about API Management, Vince is starting to become more and more confident that this date can be met. In part due to less friction than what is typically involved in these situations. Usually in these situations there are just too many teams and hand offs involved that just consumes a lot of time.
- #27 When asked how they are going to achieve the timelines, our hot shot architect mentions that since they do not need to re-write existing services they can re-use much of what has already been built.
- #28 At the architecture review board, Vince needs to present the solution to stake holders and describes all of the features in an API Management platform. He is able to address the non-functional IT requirements in addition to providing the business with the agility that it needs.
- #29 One of the key benefits of using an API Management approach is the ability to collect analytics out of the box.
- #30 Of course after the implementation goes live there is a resurgence in the confidence that the Business has for IT
- #31 Let’s take a look at what their initial architecture may have looked like. In this case we have some backend services available to BizTalk. These services include SalesForce, the cloud based customer information system. We also have a Policy System where all of the customer’s policy information is kept. A Rating engine, or Quote Calculation engine, is provided in the form of our BizTalk rules engines where customer demographic and policy information is passed to and the Rating engine is going to output a cost for our customer. Lastly we have the department of motor vehicles or the DMV which maintains a registry of cars. One of the attributes that the DMV will be maintaining is whether or not a vehicle is considered to be environmentally friendly.
- #32 Moving forward, we can introduce Azure API Management layer in front of our on-premise services. As you can see, within the enterprise there is a lot of SOAP messaging that is occurring. Mobile platforms typically do not support SOAP as JSON over HTTP is typically used instead. So using this approach we can introduce a layer of agility without changing all our backend systems. We can continue to support agent to agent communication through the traditional application(s) but we now offer a mobile application and can support new channels by allowing Partners to re-sell our policies. All of the interactions between external parties and the insurance company are secured and managed through our API Management Platform.

- #36 Mobile App Walkthrough Legacy Modernization – BizTalk has been characterized as being legacy which is a bit of a stretch but in this case were able to use our existing platform and investments in order to provide integration for a modern day use case. API Management Provisioning – We saw the Azure API Management Administration portal where we were able to create our products, define our APIs and their related operations. We were then able to enforce some policies. Dashboard and Analytics – Our Dashboard provided us with some useful operational and business analytics. We were able to determine which API operation was being called most frequently, from where and how long the interactions were talking. Products – Products are our largest conceptual container where we can enforce policies. This is where we define a product and can assign it a tier. So we may have a premium paid tier where we allow for more API calls to be made. Similarly we can provide a free tier product where we allow consumers to try out our API with little commitment or friction. APIs – APIs themselves represent our group of operations. We can also apply policies at this tier but these tend to be universal policies such as JSON-XML conversion. Operations – Lastly we have our lowest level of granularity where we have a specific operation. Policies can also be set at this level and are very specific to our API Operation. An example of this is our string replacement policy where each operation may have a unique requirement. Testing APIs – We also logged into our Developer Portal where we can test or “kick the tires” on our API. We saw that pre-built forms were available to us that contained sample data that allowed our “Time to first successful call” to be very low. We also saw code samples for many popular languages where we use that code in our applications to get up to speed very quickly Custom Policies – Custom Policies allow us to alter both requests and responses as message enter or exit our API. We can kinda look at it similar to pipelines where messages can go through different stages and one stage builds on top of a previous stage.
