The latest News and Information on Serverless Monitoring, Management, Development and related cloud technologies.


Challenges of Going Serverless (2020 edition)

While we know the many benefits of going serverless - reduced costs via pay-per-use pricing models, less operational burden/overhead, instant scalability, increased automation - the challenges are often not addressed as comprehensively. The understandable concerns over migrating can stop any architectural decisions and actions being made for fear of getting it wrong and not having the right resources.


DRY (Don't Repeat Yourself) on the cloud with Pulumi

Any enterprise working on the cloud is likely to use Infrastructure as Code as it simplifies the deployment process and makes iterative serverless applications easier to manage. There are several open source tools out there that work with most cloud providers, each of them with their own implementation processes. In this article we are going to dive into the workings of one particular tool, Pulumi.


Guide to Serverless Information Security

Information security (infosec) is a broad field. Its practitioners behave more like artists than engineers. After all, the mandate for security is not “do X”, but instead “ensure no one can do X, Y, Z, ɑ, β, ɣ, etc.”. The array of possibilities leading to infosec failure are vast. It’s like trying to prove a negative, thus making the task near impossible. On one hand we have an impossible task, on the other we have the affordance of time.


Epsagon Achieves Privacy Shield Framework Certification

July 01, 2020 At Epsagon, we pride ourselves on having a platform that is security-first and enables our users to feel confident in the privacy of their data. With this in mind, we are excited to announce that we’ve now achieved Privacy Shield Framework certification, adding to our existing certifications of SOC2 Type 2, ISO27001, HIPAA, and GDPR.


Serverless computing: The what, why, and why not

Applications have traditionally been run on servers, which have to be closely monitored to ensure there are no hindrances in production. In the case of serverless computing, you no longer have to manage servers, as the onus falls on cloud service providers. Read along to discover more about serverless computing, including some of its advantages and disadvantages. So what actually is serverless computing?


How to Debug AWS Lambda Performance Issues

Ten years ago, Amazon found that every 100ms of latency would cost them roughly 1% in sales. This is a pretty clear statement on the importance of user experience! It’s especially true in today’s ultra-competitive market where the cost of switching (to another provider) for consumers is lower than ever. And one of the most common performance issues in serverless architectures is related to elevated latencies from services we depend on.


Roadmap to Backend Developer on Cost Effective API Serverless Infrastructures

AWS API Gateway is a great service but can be quite expensive, and even cost-prohibitive in some cases. An Application Load Balancer is a viable alternative since it integrates seamlessly with Lambda functions and is also highly scalable and reliable. For very small traffic, API Gateway will probably be the winner, but in high-throughput cases, ALB is capable of providing up to 90% savings.


Expanding the Serverless War Chest With AWS EFS

On the 16th of June, AWS added to the serverless arsenal the much-coveted Amazon EFS and AWS Lambda integration, furthering an already expanding feature set of the AWS Lambda function. AWS has been continuously improving AWS Lambda since it was first released in 2014, marking the beginning of the serverless wave in cloud computing.


Using Log Data to Prevent Lambda Cold Starts

AWS Lambda enables you to run serverless functions in the AWS cloud, by manually triggering functions or by creating trigger events. To ensure your Lambda functions are running smoothly, you can monitor metrics that measure performance, invocations, and concurrencies. However, even if you continuously monitor, once in a while you are going to run into what’s termed a Lamba cold start. There are various ways to prevent AWS Lambda cold starts.


Get Notified on Slack for your CloudWatch/Lambda Error Logs: The Sigma Way

Slack is already the de-facto “channel” for team collaboration as well as low-to-moderate scale event monitoring and notifications. When we started working on the world’s first serverless MFT platform, we decided we should go down the Slack path for first-level monitoring; similar to how we already do it efficiently with our conventional AS2 Gateway.
