Oracle Cloud: Infrastructure-as-a-Service Overview
- Oracle’s Infrastructure-as-a-Service (IaaS) provides a complete infrastructure for enterprise workloads, including compute services, storage services, and network services. It enables organizations to run any type of workload in the cloud and in particular run Oracle workloads in the most optimized way.
- This gives an excellent option to clients to not purchase hardware and instead can purchase IaaS resources based on consumption
- IaaS users are responsible for managing applications, data, run-time, middleware, and Operating systems. So you still need a lot of IT resources to manage these things. It basically means your data center is in the cloud.
- IaaS Providers like Oracle still manage virtualization, servers, hard drives, storage, and networking.
- The advantage here is that users can install any required platform on top of IaaS.
Let’s take a look at various offerings by Oracle in Infrastructure-as-a-Service
Oracle Compute Cloud Service –
Oracle’s IaaS solution, Compute Cloud Service, provides elastic compute capacity, enabling you to adjust capacity to address varying business needs.
In short, it is an Infrastructure-as-a-Service solution that provides on-demand, scalable compute resources—virtual machines with the required networking and storage resources—in the public cloud.
We have the following options available with Compute cloud service
1) General Purpose Compute:
A fully scalable multi-tenant virtual compute environment to run applications with predictable, consistent performance and built-in resiliency. You can rapidly provision virtual machines on Oracle Cloud with all the necessary storage and networking resources, manage and scale your virtual machine topology in the cloud easily, and migrate your Oracle and third-party applications to Oracle Cloud. It is available in many shapes to suit your requirement
2)BareMetal servers( Dedicated compute)
- Dedicated computing provides a completely dedicated compute zone for each tenant, predictable performance, and complete network isolation.
- Basically with this offering, the Company or organization gets dedicated server hardware just as they would be on On-Premise. Bare metal compute are suitable for workloads that need to be run in nonvirtualized environments
- It has various instance types like Standard instances, Dense I/O Instances, HPC instances, GPU instances, and optimized instances
3) GPU instances
Oracle provides GPU-powered servers and VMs for high-performance computing (HPC) and AI.
They are powered by NVIDIA GPUs for a variety of use cases
4) High Performance Computing (HPC)
- Oracle provides Bare metal instances and low-latency cluster networks for high-performance computing (HPC).
- High-performance computing (HPC) on Oracle Cloud Infrastructure (OCI) brings powerful, cost-effective computing capabilities to solve complex mathematical and scientific problems across industries. OCI’s bare metal servers coupled with Oracle’s cluster networking provide access to ultra-low latency RDMA (< 2 μs latency across clusters of tens of thousands of cores) over converged Ethernet (RoCE) v2.
- HPC instances in OCI take advantage of a high-speed, low-latency network, typically utilizing RDMA (Remote Direct Memory Access) over Converged Ethernet (RoCE) for optimized data transfer rates.
5) Arm-based Compute Instance
The Oracle Cloud Infrastructure Ampere Altra A1 compute platform provides a deterministic performance, linear scalability, and secure architecture with the best price-performance in the market. Customers can leverage the industry’s first 160-core Arm server at only $0.01 per core hour and flexible virtual machines with 1-80 cores and 1-64 GB of memory per core.
6) VMware Solution
- Oracle Cloud VMware Solution is based on VMware Cloud Foundation (VCF) and provides a fully supported, customizable cloud environment for VMware deployments and migrations. The solution delivers a full-stack software-defined data center (SDDC), including VMware’s vCenter, ESXi, NSX, and vSAN. Specific use cases targeted by Oracle Cloud VMware Solution include data center and application migration, hybrid extension, on-demand capacity, and disaster recovery.
- Complete customer control
- Migrate applications without modification
- Independent scaling of compute and storage
- Predictability across operations, performance, and cost
7) Cloud Functions
Oracle Cloud Infrastructure (OCI) Functions is a serverless compute service that lets developers create, run, and scale applications without managing any infrastructure. Functions have native integrations with other Oracle Cloud Infrastructure services and SaaS applications
Important Points about the Compute Services
1) You can use one of several Oracle-provided machine images to quickly provision robust virtual machines.
Images provided by Oracle partners are available in Oracle Cloud Marketplace.
You can also build custom machine images based on the operating system and disk size of your choice and use those images to create virtual machines
2) We can configure Oracle Compute Cloud Service Linux and Solaris instances (virtual machines) to be accessed securely from remote hosts by using SSH and can configure Windows instances to be accessed securely by using RDP.
3) Oracle Compute Cloud Service is compatible with several operating systems. Some images are provided by Oracle, and some are provided by Oracle partners.
| Operating System | Versions | Image Provided by |
| Oracle Linux | Oracle Linux 5, 6 and 7 | Oracle |
| Ubuntu | Ubuntu Server 14.04-LTS amd64
Ubuntu Server 15.10 amd64 Ubuntu Server 12.04-LTS amd64 | Oracle partner |
| CentOS | CentOS 6 and 7 | Oracle partner |
| Debian | Debian 8 (Jessie) | Oracle partner |
| Microsoft Windows | 2008 R2
2012 R2 | Oracle |
| Oracle Solaris | Oracle Solaris 11.3 | Oracle |
| SUSE | SUSE Linux Enterprise Server 11
SUSE Linux Enterprise Server 12 | Oracle partner |
Oracle Network cloud service
This is another IaaS Offering from Oracle for customers. Oracle Network Cloud Service offers Site-to-Site VPN and fast-connect. Virtual cloud network, Gateways, Load Balancer. Site-to-Site VPN securely extends your on-premises network to your dedicated Oracle Compute zone
(1)Site-to-site VPN
Site-to-Site VPN offers a simple and secure way to connect your corporate network to Oracle Cloud Infrastructure over your existing internet connection. The data is encrypted using industry-standard encryption algorithms called IPSec and is then tunneled through the public internet for enhanced security and privacy.
Securely connect your existing infrastructure to the cloud by using industry-standard encryption algorithms. IKEv1 is supported today and IKEv2 will be available soon.
(2) Fast Connect
FastConnect allows customers to connect directly to their Oracle Cloud Infrastructure (OCI) virtual cloud network via dedicated, private, high-bandwidth connections. Then, based on the amount of data, customers simply choose an appropriate port speed and pay a consistent, low price each month.
(3) Load Balancer
Oracle Cloud Infrastructure (OCI) Flexible Load Balancing enables customers to distribute web requests across a fleet of servers or automatically route traffic across fault domains, availability domains, or regions—yielding high availability and fault tolerance for any application or data source. The portfolio comprises two services—Oracle Cloud Infrastructure Flexible Load Balancer (OCI Load Balancer) and Oracle Cloud Infrastructure Flexible Network Load Balancer (OCI Network Load Balancer).
Oracle Storage Cloud Service
It is an object storage solution that enables businesses to securely and reliably store files and unstructured data in the cloud. Data can be stored or retrieved, at any time, from any device connected to the Internet.
The following options are available from Oracle for this IaaS offering
Oracle Storage Cloud Service – Object Storage
This can be used to store both structured and unstructured data. Designed for enterprise-class data protection and sharing with easy access from anywhere on the internet.
Oracle Storage Cloud Service – Archive Storage
The most cost-effective storage in the industry. Designed for infrequently accessed data with enterprise-grade security, resilience, and elastic scalability. It is quite cheap and easy to use
Oracle Database Backup Service
This is for storing Oracle database backup in the cloud. This is a unique offering for Oracle database, and Oracle Database customers with direct, cost-effective integration with RMAN so you can take advantage of cloud-based data protection with current IT processes and staff.
Oracle Storage Cloud Software Appliance
It is a way to provide Oracle’s storage cloud as a secure, POSIX compliant, local NFS interface. We can use Oracle Storage Cloud Software Appliance in the data center to copy data to and from Oracle Storage Cloud Service through standard file-based network protocols.
