Managing IaaS and DBaaS Clouds with Oracle Enterprise Manager Cloud Control 12c

Chapter 2. Infrastructure as a Service

Now that we have made sure that all the necessary pieces are in place, we can start implementing a basic Infrastructure as a Service model using the Oracle Enterprise Manager Cloud Control 12c.

The IaaS model is essentially an abstraction of shared resources such as hardware, storage, and networks. The key here is that these abstract pieces of virtualized resources are provisioned on-demand according to various service levels and can be billed on the basis of actual usage (for example, storage for 1 GB may be charged at $0.00020 an hour or $0.15 a month). IaaS allows businesses to rent these virtualized computing resources instead of buying and maintaining permanent hardware. Most IaaS services offer self-service portals to provision resources. IaaS providers also provide configurable chargebacks and reporting capabilities. Correct chargeback and monitoring helps maintain SLA transparency from the provider as well as the consumer side. Oracle Enterprise...

The Oracle VM Manager setup and registration


As we discussed earlier, virtualization is the key to IaaS. Oracle VM Manager (part of Enterprise Manager) is a single interface that allows for the management of virtualized resources for your IaaS. VM Manager is the place where you create and manage virtual machines, guest VMs, virtual server pools, and zones for your IaaS. The first thing you need do is to register the VM Manager by adding it as an Enterprise Manager target (refer to the Adding targets manually section in Chapter 1, Setting Up Enterprise Manager).

Before you add Oracle VM Manager as an EM target, make sure you have imported VM Manager certificates in the agent keystore by performing the following:

  1. Export the VM Manager certificate by executing the following command on your VM Manager host:

    <JAVA_HOME>/bin/keytool -keystore <VMMANAGER_HOME>/ovmmCoreTcps.ks -exportcert -alias ovmm -file <location of the certificate>
    
  2. Import the VM Manager certificate by executing...

Networking


We will need to set up and configure logical networks that will be connected to the physical network ports on OVM Servers. This is a critical piece of setup, and we suggest you make sure your physical network components (subnets, VLANs) are correctly set up. Enterprise Manager makes this step as painless as possible, but if the underlying physical interfaces are misconfigured, there is a chance that you will encounter difficulty in debugging issues. While setting up OVM Networks, we will need to do the following:

  • Generate MAC addresses

  • Create and configure VLAN groups

  • Create logical networks

Generating MAC addresses

It is important to understand how Oracle VM Manager handles network traffic. VM Manager uses VNICs. A Virtual Network Interface Card (VNIC) is a pseudo network interface technology sitting on top of the physical network adaptor; in most cases a NIC. Each physical network interface (NIC) usually has multiple VNICs, and for a system such as Oracle VM Manager, a VNIC appears...

Configuring storage servers


The other important aspect for setting up an Infrastructure as a Service is shared storage. Virtual servers inside the server pool use shared storage mounted on external storage servers, filesystems, or LUNs. These external storage servers are available for the virtual servers via fiber channels or network communication over Ethernet.

Oracle VM Manager makes use of both standard and vendor-specific plugins to support almost all flavors of storage:

  • Local Storage: This uses the local hard disks on Oracle VM Servers. This option is not used on most real-life use cases. When the topology becomes more complex and you start thinking about HA (high availability), using replication and clustering, you will immediately realize the limitations of local storage for VMs.

  • Network Attached Storage (NAS): This is typically on NFS. Network file system (NFS) is an industry standard filesystem and can allow shared storage to VMs inside the server pool. NFS allows for flexible clustering...

Creating and configuring virtual server pools


A virtual server pool is essentially a container of one or more virtual machines or guest VMs. Server pools allow shared storage access for all the VMs and seamlessly balances the load across resources. You will, of course, need to supply enough physical resources to support the number of VMs within the server pool. Luckily, server pools can scale easily by just adding more physical resources. Let's discuss how we can create server pools:

  1. Navigate to Enterprise | Cloud | Infrastructure Home.

  2. Right-click on the OVM Target and click on Create Virtual Server Pool; you will be greeted with an elaborate screen:

  3. The VM Start Policy field allows you to decide how you want a VM to start. You can chose Start on Best Server to let Oracle VM Manager select the best server (at that point of time when VM is booted) for the VM to start. Alternatively, you can select Start on Current Server and the VM will be started on the server that created the VM.

  4. Selecting...

Monitoring and administering IaaS


Oracle Enterprise Manager offers a comprehensive management console where you can perform administration and monitoring of your cloud infrastructure. In this section, we will be focusing on how to utilize the Oracle Enterprise Manager Infrastructure Cloud Home and perform various administrative tasks.

Most of the tasks that you will be concerned with are performed either on Infrastructure Cloud Home, Oracle VM Manager Home, or Virtual Server Pool Home page. We will look at each of these portals in this section.

The Infrastructure Cloud Home page

Navigate to Enterprise | Cloud | Infrastructure Home. The Infrastructure Cloud Home page shows several valuable details under different navigation panes:

  • General: Displays a count and status of OVM Managers, zones, guest VMs, and servers.

  • Target Flux: This pane displays the number of targets created and deleted over the last month (30 days). Targets included in this graph are guest VMs, virtual servers, server pools,...

Setting up the IaaS self-service portal


We have covered quite a bit of ground in setting up a scalable IaaS. We discussed earlier how IaaS's real power is in the way users can utilize the resources via self-service portals. Self-service provisioning is the reason why most enterprises invest in IaaS, as it greatly reduces maintenance and administration costs. In the remaining part of this chapter, we will continue to understand the overall IaaS configuration using Oracle Enterprise Manager and will discuss how we can set up a self-service model using Oracle Enterprise Manager.

The self-service model allows the administrators to manage several routine configurations easily. Administrators can manage VM images, user quotas, compute, and storage resources for server pools and so on.

Let us take a detailed look at steps to set up and configure an IaaS self-service portal.

Setting up machine sizes

You can customize and configure various machine sizes you are going to offer for provisioning VMs.

Summary


We have covered quite a bit of ground in understanding the possibilities for creating a scalable Infrastructure as a Service environment. We went through various building blocks of IaaS and we reviewed all the necessary configuration options on Oracle Enterprise Manager. A successful implementation of IaaS requires careful planning and proper estimates of scale. We will talk about another implementation model of Database as a Service in the next chapter. We will also take a look at the various chargeback options available.
