This is the presentation I used at Microsoft Startup Bootcamp to cover a Serverless app development approach on Azure including various tools but primarily focusing on Azure Functions and Azure API Management.
EC2 instances, running containers, orchestrating and still worry about infrastructure. • You can have dozens of functions tightly coupled and delivered as a behemoth.
Execution Count • Premium Plan • VNet Access • vCPU / Second (Min 1) • Memory Allocated (Second) • Functions on Kubernetes – Kind of Free • Functions in App Service Plan – Kind of Free
function is invoked. • Triggers have associated data, which is usually the payload that triggered the function. • Input and output bindings provide a declarative way to connect to data from within your code.
explicitly specified intervals, like every day at 2:00 am using CRON expressions, like “0 */5 * * * *“ (every 5 minutes) • Can send information to other systems, but typically don’t “return” information, only write to logs • Great for redundant cleanup and data management • Great for checking state of services • Can be combined with other functions
relationship between functions and queues. • Middle queues are an implementation detail – conceptual overhead. • Error handling adds a lot more complexity.
7 days • Ability to playback • Big data guy. • Low latency • At least once delivery Event Grid • Sends HTTP to receiver • Distributes (dead-lettering optional, 1 day retry) • No delivery order guarantee • Deeply integrated into Azure. • At least once delivery • Low cost • Serverless
