Monitoring the availability of our service endpoints, including websites, service APIs, and specific pages is essential to the operation of any enterprise. There are many methods of performing this monitoring, including using particular software running on separate infrastructure, buying a Software as a Service (SaaS) product, or building your in-house solution.
This article looks at using Atlassian Statuspage to provide monitoring for your endpoints.
Statuspage is a service provided by Atlassian, which complements their application suite consisting of
Statuspage provides a visual indicator of the internet-accessible endpoints you are monitoring and provides…
So you created your first MySQL Aurora Serverless cluster and are ready to use it. You open your terminal client at home and type the command
mysql -u admin cluster-name-east-1.rds.amazonaws.com
and nothing happens. Well, to be more precise, the mysql client times out and exits.
The answer is simple.
Unlike RDS and Aurora Clusters, Aurora Serverless does not have a public endpoint. In fact, according to the documentation, there is no way to choose if the cluster should be public. This means working with the Aurora Serverless cluster can only be accomplished by:
AWS CloudFormation is often denigrated for not having logic flows or the ability to do some of the things traditional programming languages can. That is true to an extent. First, if you want to have total control over your CloudFormation templates using an imperative programming language, you can use the Cloud Development Kit.
Second, CloudFormation can be extended through the use of macros. In a previous article, I discussed using the CloudFormation Include macro to include a CloudFormation template inside another. This mimics the import, require commands found in other languages. …
fs = reqire("fs")
This is good as it promotes re-use and prevents “reinventing the wheel”. As a result, you can get your code written faster, deploy it sooner, and provide value to your user community.
CloudFormation cannot natively import another template or template section into the template it is processing. This is where the AWS::Include transformation comes to the rescue.
To see this…
AWS X-Ray is a method of collecting data about the work going on within a distributed application to identify performance issues and execution errors.
When execution errors happen in obscure cases, X-Ray can help identify those cases by providing a consolidated trace of each execution. This is invaluable in a distributed, event-driven or serverless application.
AWS X-Ray integrates with
Additionally, the AWS X-Ray SDK can capture metadata and requests to
Thanks to my sweetheart for picking another Raspberry Pi off my wish list, I added another Raspberry Pi 4B to my collection. (Okay, I only have two of them. So far.) I was confounded over the last few days when I couldn’t reach the Pi over the network from my iPad. My iPad Pro is my primary computing device, and I use the Pi’s as the server side for research, writing code and experimentation.
I was convinced the problem was the Pi. Everything worked before and was only flaky now there was two of them. The Pi configurations both used…
iOS 12 brought us the Shortcuts app, which was previously known as Workflow until Apple bought the application. Essentially, Shortcuts allows us to automate various aspects of our workflows or repetitive tasks. There are some limitations, which I will come back to later in this article.
The Shortcuts app is almost no-code, meaning you don’t write program code to perform the work. I say almost because you still have to design the logic flow and perform some elements of programming including variable assignments, flow control, etc. However, the drag and drop approach makes design and implementation pretty easy.
Every year, just in time for re:invent, AWS announces a plethora of upgrades to the services in the AWS ecosphere. This year is no different, even though re:invent will be completely virtual.
For anyone using CloudFormation and nested stacks, one of the major frustrations has been the inability to see what changes are being applied to the nested stacks when doing a stack update. In case you missed it, on November 18, 2020, AWS released a change to CloudFormation allowing users to see the changesets being applied to the nested stacks.
A nested stack is when one CloudFormation stack has…
I recently had the opportunity to do a little research into AWS Step Functions. What I learned was interesting and sparked some thinking about how I could improve some of my serverless projects by moving to a Step Function. This article discusses what AWS Step Functions are, how they fit into an application architecture, and their benefits.
AWS Step Functions are a “function orchestrator”, allowing you to connect multiple Lambda functions and other AWS services into an application. By moving the logic associated with the application including decisions, retries, parallel tasks, and error handling out of the Lambda functions, we…
Sometimes we are working on a project where we need a data store, but the complexities of Relational Database Service (RDS), DynamoDB, DocumentDB, et al are more than what is needed. This is where Amazon SimpleDB becomes a valuable resource.
SimpleDB is a NoSQL database. NoSQL databases are not new, having been around since the 1960s. The term NoSQL can have several different meanings from non-SQL, referring to the lack of relation support in the database, to Not only SQL meaning the database may support Structured Query Language (SQL) Wikipedia.
AWS has a number of databases to meet the…
