Business Continuity and Workload Mobility for Private Cloud (CVD Part 3)

What is Next-Gen Workload Mobility for the Private Cloud?

Enterprises across the globe have been asking for simpler ways to provide multi-site Business Continuity and Workload Mobility for applications hosted in their Private Cloud. The Cloud promises a more agile operational environment and that promise has been fulfilled to a large extent within their data centers. But many Enterprises are challenged to unlock this same agility across multi-site Cloud topologies. For example, Enterprise CTOs and CIOs have asked us directly to provide simplified Workload Mobility of critical apps between sites to give their operations teams more flexibility.

Many competitive solutions offer basic VM mobility between sites and storage replication, but do not address the rest of the application environment including: security, stateful services, network containers, tenancy, and most importantly both physical and virtual resources.

What good does it do to move a VM to a new site if the rest of the application environment is left behind causing a potential security hole?

This blogs directly addresses multi-site Workload Mobility and provides some compelling test results from our new Business Continuity and Workload Mobility Solution for Private Cloud.

How to move a LIVE 3-tier app like Microsoft SharePoint to a new site (without impacting users) 

As we all know, business critical applications require a robust service environment to operate securely across the cloud. In our example below, the application environment provides firewall and load balancing services for each tier of the SharePoint application; web, app, and database tiers. These services are stitched together using a secure Network Container that carve out a slice of resources across the data center for SharePoint. Most Enterprises and SPs use a mix of physical and virtual resources including firewalls, load balancers, VPN termination, IDS, and network switching. Many of these services create stateful connections to users, so….

  • If you perform a live migration of SharePoint to a new site, stateful connections to firewalls and load balancers need to be preserved to maintain security and TCP connections to active users.

          Broken user connections = Service disruption (that’s not good)

  • You must also provide identical security and services for new SharePoint users even though the application has moved to a new site.     

           Broken Network Services = Potential Security hole (that’s even worse)

How does Next-Gen Workload Mobility actually work?

Let’s share some test results from our new Business Continuity and Workload Mobility Solution to illustrate how we performed live SharePoint migrations to a new site (75 km away) while maintaining security, stateful services, and user connections.  Oh yes, automatically without manual intervention.

Baseline topology for Microsoft SharePoint deployed in our Private Cloud

We first deployed the SharePoint Web, App, and Database tiers in a secure network container in Data Center 1 using service orchestration, simple and easy. Refer to the figure below for a topology picture.

  • SharePoint Web Tier is in a Public Zone, and uses a virtual firewall (VSG) and Citrix load balancer
  • SharePoint App Tier and Database Tier (SQL) are in a Protected Zone and use an ASA Firewall and Citrix load balancer
  • Our validated design provides LAN extensions, extended clusters, secure network containers, virtual switching, and storage replication between Metro sites

SharePoint is up and running in Data Center 1, supporting hundreds of users with secure connections. Now let’s move SharePoint to a new site without the users knowing it.

Blog-3-App-Container-v2

Step 1:    Perform Live SharePoint Migration to Data Center 2….while maintaining secure user connections!

We performed a Live vMotion of  SharePoint (Web, App, Database) to new hosts in Data Center 2, described in the figure below.  Data Center 2 is 75 km away. Our SharePoint migration had minimal disruption (2 seconds or less) and maintained security, stateful services, and all user connections across our multi-site Cloud. Pretty sweet!   A few highlights from our validated design are provided below.

  • Our virtual switch (Nexus 1000v), virtual firewall (VSG), and UCS automatically updated Port and Security Profiles at the new site, so our virtual switching and application firewalls were preserved without lifting a finger.
  • Layer 2 Extensions permit tromboning back to Data Center 1 to maintain connections to physical appliances (stateful firewalls and  load balancers), also without manual intervention.
  • Our Network Container was automatically extended between Metro sites, maintaining security, tenancy, QoS, IP addressing, and user connections.  SharePoint was discovered on the new host in Data Center 2 within seconds, using this extended Network Container.

Now let’s move the rest of the network container to Data Center 2 in less than one second!

Blog-3-App-Move-v2

Step 2:      Redirect users to a new Network Container in Data Center 2….in less than 1 second!

With the aid of service orchestration, we simply created a new network container in Data Center 2. This new container included the same configuration, connections, and services (firewalls, load balancers) as the original container in Data Center 1.  Once created, we simply redirected external users to the SharePoint application running in Data Center 2, as described below.  The redirection of users happened in less than one second, pretty amazing. A simple routing update delivered through service orchestration performed the redirection. In this step, user connections were broken and new connections were re-established to the already running SharePoint application in less than one second!   A few highlights from our validated design are provided below.

  • Layer 2 Extensions allowed the preservation of IP Addressing for Apps and Services during migration.  There is no need to “re-IP” your applications just because they’ve moved to a different city.
  • The complete Network Container including physical and virtual resources was moved  with minimal disruption (sub-second) to users
  • Our Multi-site Cloud solution supports a typical application environment, including both physical and virtual resources, with scaling for large and small private clouds
  • We also support Cold workload moves of less critical workloads that don’t require these stringent stateful requirements.

Setting the Stage for the Cisco Mobile Workspace Solution with Citrix CVD

CiscoWotrkSpaceSolutionThe times keep changing: first there were devices, then there were apps, and today, if you don’t develop a strategy for enterprise mobility and get ahead of the trend, the mobile wave will leave you behind. A year ago, after talking with many of our customers, partners, and our own technical sales teams, we realized that IT organizations were facing enormous challenges when making the transition from simple BYOD to adopting an enterprise mobility strategy across the business. As is typical during such tremendous market transitions like mobility, IT organizations were spending a lot of time figuring out how to line up the pieces required to support a mobile workforce, sorting through and weighing the many technology and vendor choices.

Today in conjunction with our friends at Citrix, we are happy to highlight the  Cisco Mobile Workspace Solution with Citrixbuilt on the Citrix Workspace Suite. We are very excited to deliver this first of its kind, comprehensive solution to our customers. Today I’d like to take a step back and set the stage for the Cisco Mobile Workspace Solution with Citrix by taking you through our thought process in creating the right enterprise mobility solution for our customers.

Business Continuity and Workload Mobility for Private Cloud (CVD-Part2)

In my previous blog, we provided an overview of the critical use cases and innovations we included in our new Business Continuity and Workload Mobility Solution for Private Cloud.  This blog highlights the critical trends and challenges driving new multi-site Cloud designs.

Two important trends are driving CTO’s and CIO’s to deploy new multi-site Cloud solutions that provide better Business Continuity, Workload Mobility, and Disaster Recovery.

  1. More workloads are moving to the Private and Public Cloud versus the traditional data center
  2. Cloud Data Centers have a higher density of workloads per server than traditional data centers due to increased virtualization.

Cisco Global Cloud Index: Forecast and Methodology, 2012–2017

Blog 2 - Trends

This ever increasing volume of Cloud hosted workloads is placing serious pressure on operations teams to manage larger scale data centers, and insure that they keep these workloads up and running, avoiding costly downtime or a nightmare service outage.  Many of the CTO’s and CIO’s we’ve worked with are re-assessing their Multi-site strategy to insure they can answer some tough questions:

  • What are the common weak points of multi-site Cloud designs that could prevent us from achieving our Business Continuity goals for our critical apps?  Can we avoid them?
  • How can we provide Workload Mobility between sites to provide a more agile Cloud environment?
  • In the event of site outage, can our Private Cloud reduce the time it takes to recover critical applications to a new site?
  • How can our Private Cloud deliver these critical services (Business Continuity, Workload Mobility, and Disaster Recovery) with lower cost and complexity?
