In this episode, I spoke with Eduard Bargues, who is a Principal Engineer at Ohpen, a cloud-native open banking platform. We talked about Ohpen's migration from EC2 to a mix of Fargate and Lambda, and along the way, we touched on many topics: migration patterns the "serverless-first" mindset how to choose when to use Lambda vs Fargate why monolith functions are painful and should be avoided recommendations and pitfalls why you should build a DX team We also talked about how being cloud-agnostic makes you use the cloud in a way that is inefficient and creates many layers of unnecessary abstr ..read more

In this episode, I spoke with Luca Mezzalira, who is the author of "Building Micro-Frontends" by O'Reilly, and a Principal Specialist Solutions Architect at AWS focusing on serverless. We talked about micro-frontends and dived deep into his experience with them at both DAZN and AWS. We got a high-level overview of micro-frontends: what it is, how they work, and who should adopt micro-frontends. And why it worked out so well at DAZN, which had the challenge of supporting more than a dozen of devices including set-top boxes with custom versions of HTML! We were also able to dive deep into some ..read more

In this episode, I spoke with Eric Peterson who is the founder and CTO of CloudZero, a leading vendor that helps AWS customers reign in their AWS spending by revealing hidden savings and preventing costly mistakes. We discussed a range of topics, including common mistakes AWS users make and how CloudZero once saved a customer potentially a million-dollar on CDN bills by alerting them of spending abnormalities early. We also talked about the trade-off between having cloud cost controls and the cost overhead they add. We talked about FinOps and how CloudZero can understand the unit cost of the ..read more

In this episode, I spoke with Dax Raad to talk about SST and the challenges of building an open-source community. Honestly, I think AWS can learn a thing or two from Dax's approach towards open-source, an approach that puts the needs of the customers first at the cost of the convenience of the maintainers. We talked about some shortcomings of CDK, the origin of SST and what problems it's supposed to solve; who are the intended users; and how SST differs from other simpler products on the market. We talked about  Dax's journey into serverless, via Kubernetes. And the self-realization tha ..read more

In this episode, I spoke with Kirk Kirkconnell to talk about his experience with database technologies and serverless. Kirk had been involved with databases his whole career, including recently with the DynamoDB and Momento teams. We talked about single table design with DynamoDB - when to use it and some common drawbacks to consider. We discussed the strength and weaknesses of DynamoDB DAX and when to use it vs a general-purpose caching solution like Momento. But the big discussion was about the rise of faux serverless services and the important, yet often underrated role of scale to zero ..read more

In this episode, I spoke with Vijai Ramcharan to talk about his experience with introducing serverless at NN, a 175 years-old financial services company based in the Netherlands.
