I recently spoke with @w_hummer to find out what's new in LocalStack v4 - e.g. visualize and trace event-driven arch end-to-end, or create snapshots of your system. It's crazy how fast they are innovating! https://t.co/UPwN9EOzC0

Through chaos experiments the Lambda team reduced response time to an AZ outage by 90%! 🤯 https://t.co/TMlzHct4Pr

You don’t have to do chaos experiments in production. Stay in the lower environments first, you can learn a lot there and it helps you build confidence in how you run these experiments and mitigate the risk of accidentally breaking production (which is not the goal!) https://t.co/lK9kfMMAIN

SREDay, here we go! https://t.co/NtuM1zjWs1

"Lambdaliths have slower cold starts" "Lambdaliths have fewer cold starts" Both can be true, but neither is entirely correct. It depends on several factors. In my new post, I explain these nuances so you can make a better choice. https://t.co/HZXe0yE1ZD

Cognito M2M charges ~$2500 per million auth requests and other IDPs also charge a king’s ransom for M2M authentication! Instead, check out these five alternatives to allow services to communicate securely with each other. https://t.co/DiOMadr524

Sad to see Fauna go 😢 https://t.co/adAKQIU1ne

Just 3 weeks to go until my next serverless workshop 🚀 I'm working on some new content around multi-tenancy patterns and their pros and cons. Looking forward to working with a new group of students and the new perspectives they bring. https://t.co/DPGY9Imftd

The line up for AWS Community Day in Prague is looking great! But I think @tpschmidt_ and @sandro_vol need to use different profile images! https://t.co/04ZUbvjt8a https://t.co/rnWEu6J6gZ

Really nice article from the Lambda team on their architecture that handles tens of trillions of monthly invocations. It explains how async invocations work - how they handle noisy neighbours, spikes and tenant isolation. Well worth a read! https://t.co/MiwnFNBR5E https://t.co/bRzbhogHlT

New post: how to implement durable execution for Lambda with just 10 lines of code. It's not a replacement for Step Functions or Restate, but for simple use cases, like the one I had, it's all you need to make Lambda executions durable. https://t.co/IumCWeAPRe

I spoke with @ksshams about building large-scale (think millions of TPS) multi-tenant systems. We talked about pros & cons of cell-based architectures, how it reduces the blast radius, and techniques for building high-throughput systems e.g. core pinning https://t.co/YaBeGfQrCd

FundApps went serverless and it made their system faster (shaving 60% in processing time), more scalable, cheaper (saving 70% on db cost) and made their customers happier! https://t.co/jrNvNteBrn

Nice to see a full house at the serverless days Manchester! 💪 https://t.co/xdnifWBSlt

Thank you to everyone who attended my talk at the Serverless London meetup last night 🙏 Here are my slides for those who couldn't make it. You can try Evolua for free at https://t.co/jWJiLztYM8. We'd really appreciate your feedback! https://t.co/Iecj5WBXLY

I'm digging into the new Serverless Container Framework, and it's looking good! You can switch between Lambda and Fargate without rewriting your app, which is a game changer. I've only tried out their example projects, and they work as advertised. I can switch an API from
