Containerized data workloads running on Kubernetes offer several advantages over traditional VM / bare metal based data workloads including but not limited to:

● Better cluster resource utilization

● Portability between cloud and on-premises

● Frictionless multi-tenancy with versioning

● Simple and selective instant upgrades

● Robust automation framework can be embedded inside CRDs (Custom Resource Deﬁnitions) or commonly referred as ‘K8S Operator’.

● Provides GraphQL abstractions over your Database App

a. Query, mutate data via GraphQL constructs

b. Build your schema and evolve your domain models

● Evolve your API without versioning

● Provides out of the box pagination and ﬁltering GraphQL ● Collate disparate Data sources Server

● Eventing Support

HANDLING FAILURES ROLLING UPGRADES BACKUP & RESTORE

Supports two upgradeStrategies: Backups and restores are a Pod failure handled by K8S onDelete (default) and database level construct automatically rollingUpgrade

YugaByteDB can perform Node failure has to be handled Pick rolling upgrade strategy for distributed snapshot and copy manually by adding a new slave DBs that support zero downtime to a target for a backup node to K8S cluster upgrades such as YugaByteDB

Restore the backup into an Local storage failure has to be New instance of the pod existing cluster or a new cluster handled manually by mounting spawned with same network id with a diﬀerent number of new local volume to K8S and storage TServers

Can connect to ANY node HASURA Add/remove nodes anytime
