Elastic Stack

One of the best features I like is that Elastic built their own kubernetes operator to extend the k8s orchestration and make it easy to deploy, scale, change, secure and configure hot-warm infrastructures. Their operator saves a ton of time during configuration. I have deployed stacks on different k8s architectures like Azure Kubernetes Service, Amazon Elastic Kubernetes Service and small on prem clusters with microk8s without issues. When we reach performance thresholds we add more elastic nodes and ECK secures and joins it to the cluster and in minutes we can leverage the extra compute. A lot of changes that are done after going to PROD are non-disruptive since ECK is aware of the main node and makes sure to pass the master role before the main one is re-deployed. I have also migrated Elastic Cloud Enterprise deployments running on bare metal and the stability of ECK is unmatched.

Currently it is not recommended or supported for a PROD cluster to do its own self monitoring so you have to deploy a monitoring cluster. In cloud scenarios this adds costs and extra complexity so it will be great to have this feature supported.

Provides great features for log ingestion, normalisation and visualisation.
Has a free open source tier which can be used to cover many use cases.
Visualisation options are diverse and powerful.
Solid community support in forums.

Initial setup can be tedious and is rather complex.
The provided security ruleset tends to produce many false positives and requires fine tuning.
Log ingestion options are not entirely covered by the web user interface.

It is a super fast and efficient data extraction tool. Recommended for medium-sized projects.
Handles large amounts of data, is scalable.

Usable from any device, however these must be state-of-the-art and offer great calculation speeds and ram storage.
