There are two major problems with Serverless Aurora v2 that fundamentally miss the mark of true #serverless(ness). One is the inability to auto-pause (as Mike mentions), and the other is the missing Data API. These might make it unusable (for now). ☹️ Some thoughts… 🧵 Let’s start with the “scale to zero” bit. I think it’s unreasonable to expect a production cluster of Aurora to scale to zero and then be instantly accessible following a short cold start. However, this feature is crucial to development and preview environments.

The responses to Kelsey's tweet illustrate a fascinating disconnect between traditional and #serverless mindsets. If you approach "serverless" like any other compute platform, you're going to be disappointed. Here's why… 🧵 Let me start by clarifying what I mean by a "traditional" mindset. I don't mean "legacy", and I certainly don't mean "wrong". I think of it as the encapsulation and orchestration of compute processes within a single execution stack. This includes both VMs and containers.

Here is my Ode to the Cloud 2021. Happy New Year, everyone! 🍾🥂🎆 #cloud #serverless Two thousand twenty-one, a strange year we have seen,
Mixed with lots of highs and lows, and bags of in between.
And even though, most of us, just want to scream out loud,
Plenty of interesting things, did happen in the #cloud.

Great thread by @loujaybee! The @awscloud strategy has always been "build the primitives and let the ecosystem fill in the rest." But now that we have *most* of the primitives we need, what should AWS focus on next? 🤔 I don't think it's building better dev experiences. A 🧵 1/ Something very interesting happened at this year's @AWSreInvent. For the first time, all the announcements seemed "incremental" as opposed to "transformative." No new service like Lambda, EventBridge, or Step Functions, just upgrades. To me, this signals one thing: maturity. 2/

Yesterday I turned 43 and realized I've been in #tech for 24 years (I got paid to create my first "professional" website in 1997). Here's 24 things I've learned over the past 24 years. Perhaps you'll find them useful on your journey. 🧵 24. Plan work around your life, not life around your work - I worked 70+ hr weeks in my 20s & early 30s. While I'm sure there's a correlation between that & my "successes", there's also a lot of regret for missed time with family & friends.

Everyone got so excited about Graviton2 Lambda functions & Step Functions AWS-SDK integration yesterday that you might have missed this one about triggering Lambda functions from SQS queues in *different* accounts. This is important, a short 🧵 #serverless aws.amazon.com/about-aws/what… Having multiple AWS accounts to handle different parts of your application (from both a lifecycle and service perspective) isn't just good practice, it's also AWS recommended. 👍 2/9

Very cool #reInvent session by @sliedigaws about building out distributed applications using different #EventBridge patterns. Let's recap this quickly to see how we can use them to build out our #serverless apps. 🧵 The "single-bus, single-account" pattern is a super simple way to get started, especially if you have a small team. Create logical service boundaries and use a single event bus to decouple the services. This is one of my favorite ways to prototype #serverless applications.

Excellent post by @mipsytipsy on the future of Ops careers, even if it’s a bit critical of "Lambda: A Serverless Musical". 😉

While I 100% agree that #serverless isn’t headed towards the ridiculous notion of #NoOps, I have some thoughts on the article. 🧵
thenewstack.io/the-future-of-… Context is *extremely* important. The repeating line in the musical of "I'm going to reduce your… ops!" is in the context of setting up and maintaining a Kubernetes cluster. If it's not obvious the first time with "Hey yo, I'm unlike containers, no patching, no maintainers"...

.@alexbdebrie has another excellent post that details the benefits and downsides of using a Single-Table design with @DynamoDB. While I completely agree with him on the “benefits”, I have some thoughts on his “downsides” that I’d like to address. 🧵 alexdebrie.com/posts/dynamodb… Downside #1: “The steep learning curve to understand single-table design”

There is no doubt that “thinking in #NoSQL” is a complete departure from traditional #RDBMS, but understanding how to correctly denormalize data is applicable to both single- AND multi-table designs.

Very interesting take from @forrestbrazeal on the new #Lambda Provisioned Concurrency. I have a few quick thoughts on this as well... trek10.com/blog/provision… Yes, "pay-per-use" is very attractive, but I'm okay with AWS's "pay-for-value" model in #serverless environments. I don't expect the cloud to dedicate resources to me for free. I may get the benefit of warm invocations, but that's an internal optimization, not a guarantee.

Kicked off @AWSreInvent 2019 by attending @houlihan_rick’s @DynamoDB modeling session. As expected, it was a 60 minute firehose of #NoSQL knowledge bombs. There was *A LOT* to take away from this, but here are some really interesting lessons that stuck out to me. #reInvent DynamoDB performance gets BETTER with scale. Yup, you read that correctly, the busier it gets, the faster it gets. This is because, eventually, every event router in the fleet caches your information and doesn’t need to look up where your storage nodes are.

I *LOVE* what the @awscloud #EventBridge team is doing for #serverless, and this new Schema Registry is an amazing next step! Here are my initial thoughts on this... aws.amazon.com/blogs/compute/… EventBridge _should_ become the glue that ties together all your cloud services (eventually w/ two-way message bindings). This means that the number of event types (don't forget SaaS partners) is going to increase exponentially...

I've been spending a lot of time lately with @dynamodb in my #serverless applications, so I thought I'd share my surefire guide to migrating to it from #RDBMS. So here is…

How to switch from RDBMS to #DynamoDB in *20* easy steps… (a thread) STEP 1: Accept the fact that Amazon.com can fit 90% of their retail site/system’s workloads into DynamoDB, so you probably can too. 🤔
