  • Easy GoLang AWS SDK V2 Upgrade

    Easy GoLang AWS SDK V2 Upgrade

    In my day job I have a pretty extensive library of routines I use to wrap cloud automation using the vendor libraries as composed functions. That makes things like deploying a stack, or creating an AMI a bit easier. Composed functions allow me to build things in the cloud in a consistent way.  I simply […]

  • Plesk Migration to AWS

    Plesk Migration to AWS

    I have been running my hosting on 1and1 hosting (now Ionos) since the early days of the web. In the years I’ve been on that service, I’ve moved it a few times from one of their servers to another (mostly to save a few bucks), so it was time to do a Plesk migration to […]

    AWS Login Code As Infrastructure CloudFormation

  • AWS Cloudformation with Optional Resources

    AWS Cloudformation with Optional Resources

    I had a situation where I had to bypass creation of some resources in CloudFormation. Either the resources already exist, or I just don’t want to create things depending on conditions. To achieve this it turns out that CloudFormation actually has a nice facility, although it is a bit awkward.

  • Migrate JavaEE from Single Tier VM (Step 1)

      I manage a small application that is hosted on a single Linux virtual machine and have noticed some occasional performance and stability issues. The server runs CentOS, MySQL and a GlassFish server. I chose GlassFish several years ago because at the time it was the only EJB3 container around, as well as being very […]

  • Getting the correct timezone in a web application

    I support a web application that is hosted on a virtual private server. The application architecture is JavaEE running under GlassFish on CentOS. Like most ISP’s, my hosting provider builds vanilla Linux boxes that can be configured with various flavors of the OS. Out of the box these images have their timezone set to UTC, […]
