As mentioned yesterday here and here, we are very proud of Citrix CloudPlatform and the ability to handle both cloud scale-out implementation native workloads and application put to the traditional scale workloads. Let's break this statement down in details. We'll start with native cloud applications scale-out workloads.
native Cloud Scale-Out Applications
We take a look at the underlying infrastructure used to support an application for scale-out native cloud. In this scenario, the infrastructure is often built using basic materials that are not designed to fail or high availability. Any node can fail at any time. Resilience is not built in infrastructure; it is built into the application. In addition to the basic equipment of software defined services are often used, such as software-defined networking (SDN) and Software Defined Storage (SDS), generally object storage. In CloudPlatform wrap us all in one Availability Zone as shown below:
CloudPlatform New in 4.2 is the ability to use Object Storage volume snapshots as well as image models. Additionally, the storage object may be shared between availability zones for more efficient operations.
An additional feature in CloudPlatform 4.2 for native cloud applications is the concept of regions . CloudPlatform introduced regions as an additional element logical hierarchy above areas. Regions may contain more than one availability zone. Each region will have a dedicated management infrastructure to allow disbursement of scenarios and geographical disaster recovery. Regions also enable additional scalability, higher availability, and increased compliance. In addition, the storage object can be configured to replicate across regions.
Finally, back to CloudPlatform 4.2 for native cloud applications, we have a number of improvements in the daily operations of storage and networking:
- Primary Dynamic storage Provisioning provides the flexibility of storage resources in cloud environments by automating common storage management tasks and streamlining the procurement process
- advanced network cloud allowing operators of cloud to create advanced cloud network configurations and network-as-a-service in particular offers new IP portable comprehensive capabilities , Advanced load balancing scenarios (GSLB, Advanced zones) and AWS as healthy controls to ensure application availability, network resources and dedicated VLANs.
traditional Scale-Up Applications
Then we traditional scale-up applications . Start by examining the underlying infrastructure as we did above. The infrastructure typically used for this type of application is very different. Resilience is built into the infrastructure; it is not built into the application. As you can see, the infrastructure requirements for a traditional application are very different from a native application cloud. In this case, the underlying hardware is built for redundancy and resiliency and application expects this environment to maintain operations at any time. A hypervisor management server is often deployed, layer 2 VLANs, hypervisors are grouped into clusters, and the SAN is used. In CloudPlatform wrap us all in one Availability Zone as follows:
Although this topology is not new, CloudPlatform 4.2 brings significant improvements to this architecture that are worth to talk about.
The first major improvement to CloudPlatform 4.2 is better support for multi-level (n-Teir) applications and virtual private clouds (VPC). With the support n-tier, we are able to separate and firewall if needed to provide better security between each access layer. This feature when combined with the existing load balancing and anti-affinity rules / affinity allow an incredible amount of flexibility, reliability and compliance for applications n-tier, all in an environment Secure provided by VPC. An example of a typical three-tier application providing Web, application and database levels:
There are many situations (compliance, security physical, departmental budgets, performance, licensing) where dedicated resources are needed to support traditional workloads. CloudPlatform new in 4.2 is the ability to provide dedicated resources to the host, cluster, and the level of the platform. CloudPlatform supports dedicated CPU, memory, IP network, and disk
Finally, we have some additional improvements to the functionality of existing CloudPlatform that deserve to be mentioned in support traditional applications:
- VMware integrations to perform enterprise application workloads in the cloud and leveraging your existing VMware investments, configurations and expertise. CloudPlatform supports dynamic scaling of CPU and memory on the performance of virtual machines and dvswitch PVLAN and network support for the VMware VM switching and isolation on the same network. In addition, CloudPlatform enables VMware vSphere features such as hot add virtual hardware, VMotion, VMware HA and DRS, CPU & RAM overcommit, VM snapshots, migration storage and storage area off blocks.
- corporate quality network to support the performance, scale and SLA requirements of application workloads to the most demanding production. CloudPlatform integrates directly with the external auditors of application delivery business class (ADC) and networking devices, including Citrix NetScaler, Cisco hardware and software (UCS, Nexus 1000v, ASA1000v), firewalls Juniper and VMware Distributed Virtual switch. CloudPlatform also offers built-in support for DHCP, NAT, Gateway, VPN, Firewall, Port Forwarding, VLAN, Elastic IP, routing, and load balancing.
As you can see Citrix CloudPlatform 4.2 has many new features and enhancements to enable the management of ThE TWO your native cloud and application workloads traditional.
