Java’s cold start problem is real, especially on #AWSLambda. Slow response times can break SLAs & user trust. @VKazulkin shows how #SnapStart & priming with #CRaC reduce latency without rewriting your entire stack.

We just published a new 🎥 of #JCON WORLD ONLINE 2023!
Watch Vadym Kazulkin talking about 'How to Reduce Cold Starts for Java Serverless Applications in AWS: #GraalVM, #AWS #SnapStart and Co'

#Java is for many years one of the most #popular ...

Watch it now: https://youtu.be/iue7kymLE60

🥳Java 17 is now available on #AWSLambda and it has support for #SnapStart.

New language features include records (JEP 395), sealed classes (JEP 409) and multiline strings (JEP 378).

Read about the changes in our release blog

Using checkpoint/restore mechanisms allows #Java applications to startup very fast.

The #CRaC project in #OpenJDK to achieve this, led by #Azul, is gaining momentum as it has been integrated in #AWS #SnapStart for #Lambdas and multiple frameworks like #Quarkus, #Micronaut, and #SpringBoot.

Run your monolithic #JakartaEE application as AWS Lambda Function with extreme short startup times => RT AdamBien: I deployed a CraC / SnapStart @MicroProfileIO / @QuarkusIO application as AWS Lambda with CDK and compared the cold start with the snap start: adambien.blog/roller/abien/e… #Serverless #JakartaEE #snapstart

In the original post about #AWS #Lambda #SnapStart I said that there are "tricky things you need to do to make it safe and secure." Reading with fresh eyes that might be misinterpreted.

There were nuanced important problems that AWS engineers had to solve, but those don't transfer to _you_, the customer.

Quarkus has support for #Amazon #Lambda #Snapstart. The just announced technology that enables super fast startup on #AWS Lambda.

The core technology behind #Lambda #SnapStart is in the #OpenSource #Firecracker virtual machine monitor.
