Scalable API management as a service

Last updated 20 February 2019

WSO2 API Cloud is an add-on that enables you to turn Heroku-hosted web services into fully managed APIs. It is a publicly hosted version of the award-winning, open-source WSO2 API Manager. Using WSO2 API Cloud, you can:

• Design your APIs and provide a unified development experience for application developers.

• Manage your API’s lifecycle from early JavaScript prototypes to multiple versions and retirement.

• Set up a themeable, customizable Developer Portal (API Store) at your own URL.

• Manage the developer community by allowing self-signup and blocking subscriptions.

• Use API monetization capabilities and support free, commercial, and freemium models.

• Implement access control on APIs using industry standards such as OAuth and SAML.

• Automatically scale to meet the needs of any API demand.

• Route API traffic through a highly scalable API Gateway, orchestrate, and transform calls and responses.

• Monitor API usage and performance using analytics, reports, alerts, and automated fraud detection.

Provisioning the add-on

WSO2 API Cloud can be attached to a Heroku application via the CLI:

$ heroku addons:create wso2apicloud
-----> Adding wso2apicloud to sharp-mountain-4005... done, v18 (free)

After you install WSO2 API Cloud, your application should be configured to fully integrate with the add-on.

Quickstart

Spin up a simple REST service

1. Clone this sample Node.js REST service app:

   $ git clone https://github.com/wso2/cloud-heroku-samples.git
   $ cd cloud-heroku-samples
   

   This app implements a simple echo service that takes a text parameter and returns the word Hello along with the provided parameter.

2. Create a new Heroku app:

   $ heroku create
   -----> Creating https://warm-dawn-12833... done,
   -----> https://warm-dawn-12833.herokuapp.com/ | https://git.heroku.com/warm-dawn-12833.git
   

3. Deploy the sample code to it:

   $ git push heroku master
   

4. Ensure that you have at least one instance of the service running:

   $ heroku ps:scale web=1
   

5. Verify that your web service is running by appending /hello?name=World to your Heroku app’s root URL (e.g., https://warm-dawn-12833.herokuapp.com/hello?name=World) and navigating to it in your browser:

   

Create a WSO2 API Cloud account

Access the WSO2 API Cloud dashboard via the CLI:

$ heroku addons:open wso2apicloud
Opening guru301 for sharp-mountain-4005

or by visiting the Heroku Dashboard and selecting the application in question. Select WSO2 API Cloud from the Add-ons menu.

• If you do not have an account in WSO2 Cloud, the UI directs you to create one.
• If you already have an account in WSO2 Cloud, select the organization that you want to associate with your Heroku account.

After you complete the signup process, your dashboard opens:

Define a managed API

1. From your WSO2 API Cloud dashboard, click New API…

   

2. Select Design a New REST API and click Start Creating.

   

3. Provide a display name (e.g., Heroku), a context, which is the URL of your API (e.g., heroku), and a version (e.g., 1.0):

   

4. In the API Definition section, enter hello as the URL Pattern and select the GET checkbox. Click Add.

   

5. Expand your new /hello GET method and add a new parameter called name:

   

6. Click Implement:

   

7. Expand the Managed API section and provide your Heroku app’s root URL as the Production endpoint:

   

8. Click Manage.

9. Set Unlimited as your API’s tier:

   

10. For now, set API security to None:

    

11. Click Save & Publish.

12. Click Go to API Store to open your API in the API Store, which is the developer portal of the API Cloud:

    

13. In the API Store, click the API Console tab.

14. Expand your API’s /hello method, provide a value to the name parameter (e.g., World), and click Try it out.

    The API calls your backend service in Heroku and shows the execution results.

    

You have successfully created a managed API based on your Heroku service.

WSO2 API Gateway as a Heroku Dyno

WSO2 API Gateway can be deployed as your own Heroku dyno. This reduces the average response time to serve an API call, which performs all the functions, without the need to connect to other API management components.

Try WSO2 API Gateway with direct deployment on Heroku:

There are multiple advantages to this deployment model:

• Performance: You can put your API gateway close to your backend services and API subscribers, avoiding the costly extra hops to the cloud and back.
• Security and Compliance: API calls and payload data does not leave your network. This keeps your security and compliance officers happy.
• Connectivity: Your API gateway is running on Heroku, so you do not have to set up a VPN or another alternative to expose your Heroku backend to the internet.
• Low Total Cost of Ownership (TCO): Most of the infrastructure is run and maintained by WSO2 for you.

Migrating between plans

$ heroku addons:upgrade wso2apicloud:medium
-----> Upgrading wso2apicloud:medium to sharp-mountain-4005... done, v18 ($768/mo)
       Your plan has been updated to: wso2apicloud:medium

Removing the add-on

You can remove WSO2 API Cloud via the CLI:

$ heroku addons:destroy wso2apicloud
-----> Removing wso2apicloud from sharp-mountain-4005... done, v20 (free)

If you remove the WSO2 API Cloud add-on, your account at WSO2 API Cloud will be disabled one month after the next billing date.
