AWS Lambda vs. OCI API Management

Lambda excels at event-driven, short-lived tasks, such as processing files or building simple APIs. However, it's less ideal for long-running, computationally intensive, or applications that rely on carrying the state between jobs. Cold starts and constant load can easily balloon the costs.

Oracle API Manager is well suited in a business or company that make use of Apis to facilitate access of backend services and data sources by the staff or customers or both. It is also imported in situations where all actions in a system need to be attributed to specific users.

• No provisioning required - we don't have to pay anything upfront
• Serverless deployment - it gets executed only when request comes and we pay only for the time the request is getting executed
• Integrates well with AWS CloudWatch triggers so it is easy to setup scheduled tasks like cron jobs

Incentivized

• API Manager allows for REST and SOAP API's to be easily created and tracked
• API Manager allows for only certain people/applications to use the API (does this thru a subscriber service it provides)
• It also publishes the API's it is tracking so developers can easily know what interfaces already exist.
• The monitoring ability is a nice feature. The admin person can easily see how and where the APIs are currently being used

• Developing test cases for Lambda functions can be difficult. For functions that require some sort of input it can be tough to develop the proper payload and event for a test.
• For the uninitiated, deploying functions with Infrastructure as Code tools can be a challenging undertaking.
• Logging the output of a function feels disjointed from running the function in the console. A tighter integration with operational logging would be appreciated, perhaps being able to view function logs from the Lambda console instead of having to navigate over to CloudWatch.
• Sometimes its difficult to determine the correct permissions needed for Lambda execution from other AWS services.

Incentivized

• Absence of Role-Based Access. A finer grain control on what type of users can call certain API Endpoints is needed.
• Performance with third-party databases isn't as fast as using Oracle Database.
• Long learning curve. Although Oracle API Manager provides performance and a vast deal of features, a certain level of expertise is required to effectively make use of them.

I give it a seven is usability because it's AWS. Their UI's are always clunkier than the competition and their documentation is rather cumbersome. There's SO MUCH to dig through and it's a gamble if you actually end up finding the corresponding info if it will actually help. Like I said before, going to google with a specific problem is likely a better route because AWS is quite ubiquitous and chances are you're not the first to encounter the problem. That being said, using SAM (Serverless application model) and it's SAM Local environment makes running local instances of your Lambdas in dev environments painless and quite fun. Using Nodejs + Lambda + SAM Local + VS Code debugger = AWESOME.

Amazon consistently provides comprehensive and easy-to-parse documentation of all AWS features and services. Most development team members find what they need with a quick internet search of the AWS documentation available online. If you need advanced support, though, you might need to engage an AWS engineer, and that could be an unexpected (or unwelcome) expense.

AWS Lambda is good for short running functions, and ideally in response to events within AWS. Google App Engine is a more robust environment which can have complex code running for long periods of time, and across more than one instance of hardware. Google App Engine allows for both front-end and back-end infrastructure, while AWS Lambda is only for small back-end functions

Oracle API Manager is much easier to learn and understand then IBM Data Power Gateway and IBM API Connect. We selected Oracle API Manager in our company because to have a good intuitive interface with drag and drop features and because beginners and easily get up to speed to use this tool.

• Positive - Only paying for when code is run, unlike virtual machines where you pay always regardless of processing power usage.
• Positive - Scalability and accommodating larger amounts of demand is much cheaper. Instead of scaling up virtual machines and increasing the prices you pay for that, you are just increasing the number of times your lambda function is run.
• Negative - Debugging/troubleshooting, and developing for lambda functions take a bit more time to get used to, and migrating code from virtual machines and normal processes to Lambda functions can take a bit of time.

Incentivized

• Oracle API Manager supports both REST & SOAP API's.
• Secure and attributable connection to back-end services and data sources. In addition to creating API's for querying data, you can also create API endpoints that can manipulate the data in the back-end databases.
• Although Oracle API Manager provides performance and a vast deal of features, to start with it is really important you train your people working on development, deployment and administrators to effectively use Oracle API Manager.
