Some thoughts about working with/on AWS

By | AWS, Database Administration & Monitoring | One Comment

In the last year working with/on AWS has become an almost daily task in my life as a consultant and trainer. From a trainer perspective there is not much to say about it because we use a very limited amount of services (EC2, mostly) and we have a limited amount of trainers that use the platform to deliver our trainings. When the amount of services you use is small and the amount of people managing…

Rapid PostgreSQL cloning using AWS EBS snapshots

By | AWS, Cloud, Database Administration & Monitoring | No Comments

When you go for AWS EC2 instances to host your PostgreSQL deployments and you want to rapidly clone PostgreSQL instances for development or testing purposes you can make use of AWS EBS snapshots. In this post we’ll look at how you can quickly spin up EC2 instances that use these snapshots as a base for new PostgreSQL clusters. Although we’ll be using the AWS console to show how this can be done you should use…

Using AWS Storage Gateway as a backup target for PostgreSQL – Cached volume gateway

By | Database Administration & Monitoring | No Comments

In the last post we had a look on how you can use AWS Storage Gateway as File gateway to store your PostgreSQL backups safely offsite on AWS S3. Another method of doing that would be to use “Cached Volume gateway” instead of the File gateway we used in the last post. The volume gateways does not provide access via NFS or SMB but does provide a volume over iSCSI and the on-prem machines will…

Using AWS Storage Gateway as a backup target for PostgreSQL

By | Cloud, Database Administration & Monitoring | No Comments

In the last post we had a quick look at AWS Kinesis data streams and how you can push data to AWS S3 using AWS Firehose. Another great AWS service is AWS Storage Gateway and in this post we’ll use that to push our PostgreSQL backups to AWS. The primary usage of AWS Storage Gateway is to extend you local storage to AWS so that you do not have to extend your local storage on…

Migrating an Oracle instance to AWS Aurora – 3 – Data replication with AWS DMS

By | Database Administration & Monitoring | No Comments

If you followed the last two posts in this little series (here and here) this is the current status of this demo migration project: We have converted the Oracle SH schema and applied it to the target AWS Aurora with PostgreSQL compatibility instance. This worked quite well but a few objects (mostly PL/SQL procedures) would need manual actions. The next and final step is to replicate the data from Oracle to the Aurora instance using…

Running SQL Server on the Oracle Free tier

By | Cloud, Oracle, SQL Server | 2 Comments

By Franck Pachot The Oracle Cloud is not only for Oracle Database. You can create a VM running Oracle Linux with full root access to it, even in the free tier: a free VM that will be always up, never expires, with full ssh connectivity to a sudoer user, where you are able to tunnel any port. Of course, there are some limits that I’ve detailed in a previous post. But that is sufficient to…

Deploying your own PostgreSQL image on Nutanix Era

By | Database Administration & Monitoring | No Comments

Some days ago we had a very good training on Nutanix. Nutanix is a Hyper-converged infrastructure and that means that all is software driven and the system can be deployed on many hardware configurations. I will not go into the details of the system itself but rather look at one component/module which is called Era. Era promises to simplify database deployments by providing a clean and simple user interface (and an API) that provides deployment…

A day at DevOps World in Lisbon

By | DevOps, Docker, Kubernetes | No Comments

On this second day here at DevOps World in Lisbon, I built a very interesting and intensive program of sessions to attend which I will explain to you more in detail below. This was also the opportunity for us (Arnaud and I) to meet our main customer from whom we are working with Jenkins X each day. It is always interesting to be able to meet physically the people with whom we collaborate, even if…
