As companies move more of their applications to the cloud, reliable internet connectivity becomes more important. Availability and uptime are mission-critical when your business depends on being connected, and failure of network equipment is a risk that should be considered.
That’s why we’re excited to introduce Bigleaf’s updated High Availability solutions for our on-site equipment.
Simplifying High Availability (HA)
Those of you who know Bigleaf know that our on-site router is a key part of our SD-WAN solution. A customer plugs their firewall(s) and ISPs into that router to connect to the Internet via our Cloud Access Network.
Previously, customers who wanted to prevent downtime in the (albeit unlikely) event of a hardware failure could deploy our HA solution that used two Bigleaf routers and two Bigleaf managed switches. This sophisticated solution provided the ultimate in hardware redundancy, preventing outages from any single piece of equipment or cable failing. But that sophistication came with tradeoffs. It’s an expensive and complex solution, with four devices taking up four rack units in a customer’s rack, and it often was overkill for many customers’ environments.
So we spoke to our customers and reexamined our deployment model. And we looked at how our friends in the firewall space approached redundancy by connecting dual firewalls to a customer’s ISPs so that if an Ethernet cable or a router fails you may lose a single ISP connection but traffic will keep flowing. We found that we could address our customers’ needs and environments with a simpler high availability solution that used fewer devices, was easier to deploy and came with lower setup costs.
Updated Equipment Redundancy Options
Our new HA solution mirrors the industry standard way of deploying high availability in network edge hardware. The result is a simpler implementation for those customers who don’t need LACP-based link aggregation (or LAGs), and for those who do, we still support it with our switch add-on.
You now have three options to pick from when addressing your equipment redundancy goals:
Bigleaf HA – Our new standard high-availability package consists of two Bigleaf edge routers connected together for immediate failover should either router fail for any reason. This provides the most cost-effective, zero-touch failover option and allows customers to deploy Bigleaf HA in a small footprint. This option does not support LACP link-aggregation, so each customer firewall will generally connect via one cable to a Bigleaf edge router.
Bigleaf HA with switch add-on option – If you can make use of LACP-based link aggregation between your firewalls and the Bigleaf equipment, this option adds two Bigleaf-managed switches that enable dual-cabling each firewall to the Bigleaf equipment, increasing redundancy.
Warm Spare – Our warm spare solution provides a lower-cost option that provides hardware redundancy but uses a manual swap-out procedure. The Warm Spare package consists of one active Bigleaf edge router and a second “warm” router that is kept online and updated, so it can be manually swapped out in the case of a hardware failure in the primary router.
We’re dedicated to making the move to the cloud simpler and more cost-effective for customers and giving our partners better ways to manage their deployments more efficiently. To get started with Bigleaf high availability or warm spare, request a quote or send us a message.
