As many organizations look to the cloud as a way to improve agility and flexibility, as well as to try and cut down their infrastructure support and maintenance costs, they are introduced to new cloud terminology: “Bare Metal Cloud,” or “Dedicated Instances.”
Let’s start by describing Oracle Bare Metal Cloud Services: A dedicated physical hardware/server with no other tenant residing and running workload on it. Bare Metal Cloud Services basically let you lease or rent dedicated physical hardware resource for running isolated workloads at an optimal cost. Depending on the cloud vendor, billing can be metered (hourly) or non-metered (monthly fixed cost).
When compared to the traditional public cloud, which is a Hypervisor Cloud that has many tenants per physical machine sharing hardware resources, Bare Metal Cloud Services is a dedicated physical hardware resource for isolation and performance comparable to on-premises hardware.
Flexibility is a key benefit of Oracle Bare Metal Cloud Services. It gives you complete control over cloud resources, so you can setup and customize based on your requirements. Basically, you have direct physical access to the resources when compared to typical cloud offerings where physical resources are hidden behind the hypervisor layer.
Bare Metal Cloud Services also allows a hypervisor on top of the dedicated physical resources, giving you the best of both worlds: allowing you to control the number of virtual machines and the workload on them. It is also important to understand that Bare Metal Cloud Services flexibility comes with a price — it takes a little longer to provision cloud resources, introducing time and complexity to the provisioning process.
Given the added complexity, you might ask why you would opt for Bare Metal Cloud Services. It’s the same reason customers opt for IaaS versus PaaS / SaaS cloud models. You have more control over your environment to install and configure your applications; you start to lose that control as you climb up the cloud stack from IaaS>>>PaaS>>>SaaS models.
Bare Metal Cloud Services offers agility for fast provisioning and on-demand resources, as well as high flexibility to define your servers, network, storage and security based on your requirements. All this makes Bare Metal Cloud Services a great alternative to traditional cloud offerings.
Performance is a major concern for organizations when it comes to moving their workload to the public cloud. Migrating to a traditional cloud environment can be considered risky for some environments because going from on-premise dedicated hardware to virtualized shared-cloud resources can introduce performance issues. Also, applications that require high memory and CPU sometimes do not fit well into the traditional cloud model. Bare Metal Cloud Services can offer Memory, CPU and Storage Allocations that the traditional shared-cloud service model cannot.
Though many public cloud vendors have not published concrete performance metrics, performance degradation can often occur due to the introduction of hypervisor layer as well as the inherent performance issues from a fully shared resource. Basically, public cloud is a shared environment where multiple Virtual Machines are fighting for the same physical resources, so performance degradation is to be expected. Therefore, if performance is key to your applications, then Bare Metal Cloud Services is probably the best option to run your application in cloud.
Bare Metal Cloud Services let you run your workload on dedicated physical servers without any noisy neighbors running their workload on the same server. This also allows you to troubleshoot performance issues more easily as you are the sole owner of the physical server, and you exactly understand what other type of workload is being run by other applications.
Like performance, security is a major concern for organizations when considering moving their environments to the public cloud. Cloud security is about requirements and capabilities to provide layers of security. It does not mean that Bare Metal Cloud Services is more secure than a traditional public cloud, but since you have more control, you can install and configure additional layers of security to further improve the security.
Additionally, because Bare Metal Cloud Services is a single-tenant solution, it provides you isolation, which can be an important compliance requirement for your organization. This allows the possibility that many security-sensitive organizations can move their workload to the public cloud by being able to conform to regulatory compliance requirements.
Furthermore, there are some software vendors who do not support or accept licensing on virtualized hardware because of soft partitioning because it’s hard to determine actual number of required software licenses for any given virtualized server in cloud. In this scenario, Bare Metal Cloud Services can be considered a viable public cloud option to satisfy licensing requirements for any application or a software vendor.
The Oracle Bare Metal Cloud Load Balancing Service provides automated traffic distribution from one entry point to multiple application servers while increasing capacity (concurrent users) and reliability of applications. Here is the brief description of benefits, limitations and load balancing policies of Oracle Cloud Load Balancing Service.
Load Balancing Policies
You can apply following policies to control traffic distribution to your backend application servers.
As many of you already know, Oracle has been working on developing a Modern Cloud. Oracle modern Cloud, let’s call it Oracle Cloud 2.0, designed to provide extreme performance for your critical applications which you might not be able to migrate on shared virtualized hardware. Oracle new bare metal cloud database service will let you quickly create an Oracle Database System with one or more databases on it. A DB System is a dedicated bare metal instance running Oracle Linux 6.8.
Similar to Oracle Cloud 1.0, new bare metal cloud database service supports following editions. It is also important to note that when you launch a DB System, you select a single Oracle Database Edition that applies to all the databases on that DB System. The selected edition cannot be changed later.
As of now, following database versions are support with all above editions but I am sure 18.104.22.168 will be available soon.
As of now, this service is only available in two shapes and only uses locally attached NVMe storage. This is good news for customers who are looking for cloud vendor, who can provide extreme performance for their applications. The available shapes are:
With the announcement of Bare Metal Cloud Service, Oracle takes a significant step toward providing complete cloud solution to its customers. With Bare Metal Cloud Service, Customers will be able to setup whatever operating system they want on top of the hardware. Oracle Bare Metal Cloud services offer many solutions but the guiding principle is that the servers and resources will be bare metal. Oracle will handle all of the network virtualization work and provide tenants, physical isolation of workloads from other cloud tenants and the provider itself.
As of now Oracle Bare Metal Cloud is offering following services:
Computer Service: Provides two compute offerings for flexibility to run your most demanding workloads, Bare Metal Instance (Fully dedicated bare metal servers on a software-defined network) and Virtual Machine Instance (Managed Virtual Machine (VM) instances for workloads not requiring dedicated physical servers)
Block Volume: Offers persistent IO-intensive block storage option (Block Volume). Block Volume Service provides high-speed storage capacity with seamless data protection and recovery.
Object Storage Service: The Oracle Bare Metal Cloud Object Storage Service is an internet-scale storage platform that offers reliable and cost-efficient data durability
Networking Service: With This offering, you will be able to extend your network from on-premise to the cloud with a Virtual Cloud Network
Identity and Access Management Service: The IAM Service helps you set up administrators, users, and groups and specify their permissions
Database Service: offer dedicated hardware for you Oracle databases in cloud environment.
