[TBD]Understanding Oracle cloud

Background

Why cloud?

• • High availability

  • Scale

  • Faster to deploy

  • Billing as per use

  • Capability to replenish when not needed

Cloud Architecture

• Oracle's public and government cloud is offered through a global network of Oracle-managed data centers, connected by an Oracle-managed backbone network.

• Oracle's Exadata Cloud at Customer leverages this network for control plane services.

• Oracle deploys their cloud in Regions, typically with two geographically distributed regions in each country for disaster resiliency with data sovereignty.

• Inside each Region are at least one fault-independent Availability Domain and three fault-tolerant Fault Domains per Availability Domain.

• Each Availability Domains contains an independent data center with power, thermal, and network isolation.

Offerings

Oracle Cloud provides

• Infrastructure as a Service (IaaS),

• Platform as a Service (PaaS),

• Software as a Service (SaaS), and

• Data as a Service (DaaS)

Compute

• Virtual Machine

• on-demand Bare metal servers and Bare metal GPU servers, without a hypervisor

Deployment model

• Public cloud (Oracle-managed regions)

• Private cloud

• Oracle-managed database-only service or full-service dedicated region

Storage

Block Volumes, File Storage, Object Storage, and Archive Storage with capability to enable database, analytics, content, and other applications across common protocols and APIs

Networking

• fully configurable IP addresses,

• subnets,

• routing, and

• firewalls

Data Management

It offers a data management platform for database workloads as well as hyper-scale Big Data

• Streaming workloads including OLTP,

• data warehousing,

• Spark,

• machine learning,

• text search,

• image analytics,

• data catalog, and

• deep learning.

The platform allows Oracle, MySQL, and NoSQL databases to be deployed on demand as managed cloud services. Oracle Databases uniquely offer the Oracle Autonomous Database (optimized for data warehouse, transaction processing, or JSON), the Exadata shape, as well as Real Application Clusters (RAC).

Business analytics

Provides Business Analytics Platform which can analyze and generate insights from data across various applications, data warehouses, and data lakes.

Management
