HotLink DR Express

  1. 1. HotLink DR Express 3.0 - DR on AWS - 21/02/2014
  2. 2. HotLink DR Express RTO: Recovery Time Objective ‘How long will it take for the system to be operational after a disaster?’ - RTO is an agreed target of the maximum time taken to restore a service – e.g. 8 hours
  3. 3. HotLink DR Express RPO: Recovery Point Objective ‘How much data will I lose?’ - RPO is an agreed target of the maximum amount of data loss acceptable after a disaster - Typically specified in hours since the last good backup
  4. 4. Traditional DR Models Cold Standby – Offsite backup tape storage. Maybe dedicated replacement hardware/facilities in storage. [RTO=weeks, RPO=24hrs]. Cheap(ish) Warm Standby @ Secondary Datacenter – Dedicated Datacenter, periodic replication of some data. [RTO=hours/days, RPO=15mins-24hrs] Expensive but essential for many. Hot Standby @ Secondary Datacenter – Expensive real-time replication of data, automated failover. [RTO<5 mins, RPO=sub-second].Too expensive for most.
  5. 5. DR - RTO in minutes/VM - RPO Configurable for each individual VM - (typically 15 mins to 2 hours) + Backup - Consolidate older Recovery Points to once per day (configurable). Store up to 500 Snapshots/VM HotLink DR Express
  6. 6. HotLink DR Express – AWS Components Datacenter Equivalent Amazon AWS Equivalent vSphere VM - Virtual Machine EC2 - Elastic Cloud Computing - 1vCPU, 2GB RAM - m1.small - 1vCPU, 4GB RAM - m1.medium - 2vCPU, 8GB RAM - m1.large - 4vCPU, 16GB RAM - m1.xlarge Primary Storage (SAN) EBS - Elastic Block Storage Near-Line Storage (disk-based backup data, archives) S3 - Simple Storage Service Internet Firewall ‘Security Groups’ Datacenter LAN VPC – Virtual Private Cloud WAN ‘Hardware VPN’ (+VPC) (rough guide for VMWare admins unfamiliar with AWS – AWS capabilities differ from VMWare and can’t be accurately compared)
  7. 7. Hypervisor Host (ESX Server) Virtual Machines Primary (SAN) Storage Near-Line (Backup) Storage Network Switches Network Firewall Internet Connection Hypervisor Host (ESX Server) Virtual Machines Primary (SAN) Storage Near-Line (Backup) Storage Network Switches Network Firewall Internet Connection Replication Replication Power and Cooling Rack/Floorspace Power and Cooling Rack/Floorspace DC Management DC Management Production Datacenter DR Datacenter Traditional Warm/Hot Standby VMWare DR
  8. 8. Production Datacenter Hypervisor Host (ESX Server) Virtual Machines Primary (SAN) Storage Near-Line (Backup) Storage Network Switches Network Firewall Internet Connection AWS Cloud - BAU Near-Line (S3) Storage Network Firewall (VPN) Replication Power and Cooling Rack/Floorspace DC Management HotLink DR – Business as Usual state (no disasters)
  9. 9. Production Datacenter Hypervisor Host (ESX Server) Virtual Machines Primary (SAN) Storage Near-Line (Backup) Storage Network Switches Network Firewall Internet Connection AWS Cloud - BAU Near-Line (S3) Storage Network Firewall (VPN) Replication Power and Cooling Rack/Floorspace DC Management HotLink DR – Business as Usual state (no disasters) AWS Cloud – DR Invoked Virtual Machines (EC2) Primary (EBS) Storage Near-Line (S3) Storage Network Firewall (VPN)
  10. 10. How it works – Backups & Replication HotLink DR Express automatically: - Clones a VM - Converts VM from VMWare to AWS EC2 format - Uploads VM to AWS S3 Storage - Takes periodic snapshots and uploads changes to AWS S3 HotLink DR Express
  11. 11. How it works – Recovery HotLink DR Express automatically: - Moves selected VM Snapshot from S3 to EBS - Creates EC2 VM - Powers on EC2 VM with attached storage - Connects EC2 VM to VPC network and assigns DHCP IP Address HotLink DR Express
  12. 12. What it looks like – Admin consoles Protection, replication and recovery all performed through familiar vCenter console vCenter plugin shows protection options – can enable/disable protection and set/modify RPO and consolidation of snapshots easily per VM HotLink DR Express
  13. 13. HotLink DR Express What it looks like – Admin consoles 2 additional Datacenters shown in vCenter: - ‘DR Express’ – shows ‘shadow’ versions of production VMs. Select a snapshot from here to recover (using standard snapshot manager menu) - ‘EC2’ – shows recovered VMs, running on EC2
  14. 14. HotLink DR Express Recovery Features - Can recover single VM to multiple points in time - Recovered VMs include their snap timestamp in their VM name - All recovered VMs auto-configured for DHCP when started on EC2 – can modify IP settings after boot. - Can recover VMs individually, or in batches - Recover to EC2, or back to your datacenter (after DR event is over)
  15. 15. HotLink DR Express Whole Datacenter failover Requires additional planning, additional components: - Secondary vCenter installation running on AWS
  16. 16. AWS VPC – Example Configuration
  17. 17. Component Limit Comments VPCs per region 5 Subnets per VPC 200 Internet gateways per region 5 One per VPC Virtual private gateways per region 5 One per VPC Customer gateways per region 50 VPN connections per region 50 Ten per virtual private gateway Route tables per VPC 10 Including the main route table Entries per route table 20 Elastic IP addresses per region for each AWS account 5 Amazon EC2 has a separate limit for its Elastic IP addresses per region for each AWS account Security groups per VPC 100 Rules per security group 50 Security groups you can assign to an instance in a VPC 5 Network ACLs per VPC 50 Rules per network ACL 20 BGP Advertised Routes per VPN Connection 100 AWS VPC Limitations (acceptable)
  18. 18. HotLink DR Express Supported Platforms Host Platforms - Amazon EC2 (all regions worldwide) Guest Operating Systems - Red Hat Enterprise Linux Server 5 (RHEL 5.4, 5.6, 5.8) - Red Hat Enterprise Linux Server 6 (RHEL 6.0, 6.2) - CentOS versions of these Red Hat releases - Windows Server 2008 R2 and R2 SP1 - Windows Server 2012 VMware vCenter - VMware vCenter 5.1 Current Supported Version = vSphere 5.1 [Support for vSphere v5.5 expected very soon (Q1 ‘14)] Initial replication (seed) of VMs is dependent on Internet Bandwidth at primary datacentre, could take a while to protect large environments - Can use Amazon Connect (avail through some ISPs)
  19. 19. HotLink DR Express Cheap – only pay for DR resources when you need them Reliable AWS infrastructure (including S3 Storage) Familiar vCenter integration Unique technology to translate VMWare and EC2 Images Affordable initial investment – start small (30VMs) and scale up as required.
  20. 20. HotLink DR Express Unique Capability use case – DR protection in a hurry “Bob is the CIO of a small/medium enterprise (100 production servers). Regulatory requirements require a Business Continuity Plan. He has 2 weeks to install configure and test an IT Disaster Recovery plan before a compliance Audit” - Deploy infrastructure in as little as a single day (depending on networking requirements) - Initial Seeding performed in batches, can be fully protected within days (bandwidth dependent) - This can be reduced with Amazon Web Connect - Can demonstrate recovery capabilities at any time without impacting production servers
