Whenever migrating a SQL Server database from on-prem to AWS Cloud, my first preference is always to move it to AWS RDS, the managed database service. So whenever a client asks me to migrate an on-prem SQL Server database, my first question is:

Its very interesting to note down that where some database providers especially in the cloud are going about diverging the database offering for various use cases, whereas Oracle is talking about converged or unified databases for various on-prem and Cloud use-cases.

In order to guarantee which pod goes to which node in a Kubernetes cluster, the concept of Taints/Tolerations and Node Affinity is used. With Taints/Tolerations, we taint a node with a specific label, and then add those labels as toleration in the pod manifest to ensure that if a pod doesn't have that toleration, it won't be scheduled on that tainted node. In order to ensure that, this tolerated pod only goes to tainted node, we also add an affinity within the pod manifest.

One of the common ways of one-to-many replication setups in Oracle databases involve, on high level, having one master transaction database which holds the transactions, then a mview log is created on that table.

The key differentiator between a NoSQL database like AWS Dynamodb and a relational database like Oracle is of the way data is modelled. In a relational model; data is normalized, de-duplicated and relationships are established between entities. In a NoSQL database like Dynamodb, data can be duplicated and entities can be fused together. This is done to facilitate scalability which is hallmark of today's hyper-scale cloud based applications.

The word Kubernetes comes from the Greek word 'Helmsman'. A helmsman is the person who navigates the ship ensuring the steady and desired course. Whether the seas are turbulent or not, or if some component of ship fails, or the load of containers on ship needs to be re-balanced; its the job of Helmsman or Kubernetes to make sure ship maintains its desired state until it reaches its destination.

Spatial is the technology of future. Massive amount of data will be generated, cleansed and stored. Oracle's autonomous databases in Oracle's cloud are ready to take on the challenge with a bang with a solid database offering, which is time tested.

In kubernetes, everything is a code. For code, the best place to reside is any git repository which should act as single source of truth. GCP Anthos enables us to extend the power of kubernetes to multi and hybrid clouds. With this power comes the added complexity of managing multiple kubernetes clusters scattered in GKE, or in GKE on-prem or in other cloud providers.
