What are the storage options in Keycloak?

Keycloak storage is divided into the following storage areas: Realms, clients, users, groups, roles, client scopes, authorization services, events, authentication sessions, user/client sessions, login failures, action tokens, and single-use tokens (last two areas to be merged in Keycloak 20).

How does Keycloak store data?

Keycloak stores by default the users data in its own database. But you can also connect to other data sources, if you already have some (legacy) stores or simply don't want to store your users data in Keycloak itself.

Which database does Keycloak use?

Supported databases

By default, the server uses the dev-file database. This is the default database that the server will use to persist data and only exists for development use-cases.

What is the minimum RAM for Keycloak?

At least 512M of RAM. At least 1G of diskspace. A shared external database like PostgreSQL, MySQL, Oracle, etc. Keycloak requires an external shared database if you want to run in a cluster.

What are the 3 types of storage methods?

Data can be recorded and stored in three main forms: file storage, block storage and object storage.

What are the 3 main types of storage currently?

There are three main categories of storage devices: optical, magnetic and semiconductor. The earliest of these was the magnetic device. Computer systems began with magnetic storage in the form of tapes (yes, just like a cassette or video tape). These graduated to the hard disk drive and then to a floppy disk.

Does Keycloak use a database?

Keycloak comes with its own embedded Java-based relational database called H2. This is the default database that Keycloak will use to persist data and really only exists so that you can run the authentication server out of the box.

Is Keycloak outdated?

Default distribution is now powered by Quarkus

The WildFly distribution of Keycloak is now deprecated, with support ending June 2022. We recommend migrating to the Quarkus distribution as soon as possible.

Do we need database for Keycloak?

Although Keycloak provides a cache layer to avoid database hits as much as possible, a good database will help to make the system behave better when data needs to be loaded from the database. By default, Keycloak is configured with a very simple H2 database that should not be used in production, by any means.

Is Keycloak scalable?

- External Infinispan cache: Infinispan cache has been externalized, three node cluster is deployed separately from keycloak servers, hence any release in keycloak will not impact existing user sessions. - Scaling: Both horizontal and vertical scaling is possible whenever scaling is needed on infinispan.

Does Keycloak use JWT?

This demonstrates how to generate JWT token using Keycloak. This can be used to authenticate the API user as well as to enable OAuth 2.0 authorization for all OAuth protected APIs using OpenID Connect in the Storefront application. This can be used as an alternative to the Auth microservice.

Is Keycloak an LDAP?

Keycloak does have an builtin ldap-provider that you can use to get users from an external ldap server so that these users can user OIDC or SDAML. But keykloak does not provide any builtin ldap server, so you can not connect via ldap to keycloak.

Does Keycloak cost money?

Keycloak is a free and open source Identity and Access Management solution aimed at modern applications and services. It makes it easy to secure applications and services with little to no code.

Is Keycloak free for commercial use?

Is Keycloak free? Yes, as for now Keycloak is open-source and has Apache License 2.0.

Is Keycloak good for production ready?

Keycloak is ready for production

Before doing so yourself, make sure to go through the production-readiness documentation.

What are some storage area options?

Three types of network storage options have typically been available: direct-attached storage (DAS), network-attached storage (NAS), and storage area networks (SAN).

How many storage options are there?

There are two types of storage device used as secondary storage in computers: HDD and SSD. While HDDs are the more traditional of the two, SSDs are fast overtaking HDD as the preferred tech for secondary storage.

What are the types of storage in server?

The four server storage types are direct-attached storage (DAS), network-attached storage (NAS), storage area networks (SAN), and cloud storage. Each has pros and cons, and a typical customer could use two or even all these types of storage.

What is better than local storage?

Cloud storage is the best solution compared to local storage when there is only a small amount of data.
