JetStream Software will be exhibiting at VMworld 2018 in the New
Innovators Pavilion, August 26-29, 2018, in Las Vegas.

"Data protection is the most common use case for enterprise hybrid
cloud," explained Tom Critser, co-founder and CEO of JetStream Software.
"So it is no surprise that the market is moving away from legacy
snapshot-based replication architectures and adopting continuous
replication methods for cloud-based data resiliency."

Advanced Design for Data Protection Services

The JetStream Data Protection software provides a spectrum of data
protection capabilities for an on-premises VMware environment, including:

  • Non-disruptive continual data replication to the cloud for recovery
    and failover
  • Virtual machine failover to a cloud-based business continuity service
  • Virtual machine backup to cloud-based NFS stores and/or object stores
  • Policy-based availability for cost-efficient SLA management per
    recovery group
  • Extreme low-latency logging on non-volatile memory

Continuous Data Capture Through IO Filters

Many traditional backup technologies still capture data in intermittent
snapshots, which introduces latency in application performance and
limits the minimization of recovery point objectives (RPO). As an
alternative to snapshots, some technologies capture data input-output
(IO) through software agents or virtual appliances, methods that
introduce a number of performance and compatibility problems.
Continuously capturing data through an IO Filter does not suffer those

In VMware environments, the JetStream solution enables continuous data
capture through the VMware vSphere APIs for IO Filtering (VAIO),
ensuring compatibility with the entire VMware environment, including any
type of on-premises hardware such as SAN, NAS, Virtual SAN or other
hyperconverged infrastructure (HCI). Because it employs the VAIO
framework for continuous data capture, the solution doesn't require
software agents in the virtual machines, doesn't require a virtual
appliance in the data path, and is a fully supported VMware Ready

The JetStream Software engineering team collaborated with VMware as the
co-design partner for the IO Filter API framework. JetStream Software
has already released two products based on the IO Filter APIs: JetStream
Accelerate for cloud resource and performance optimization and JetStream
Migrate for seamless live migration of VMs to the cloud.

JetStream Cross-Cloud Data Protection

The key components of the JetStream Data Protection software include:

  • IO Filter: the software component deployed to each VMware host for
    continuous data capture for every virtual machine in the protected
    recovery group
  • Data Availability Policy Engine: the management component that defines
    data replication and instance recovery policies for each recovery group
  • Low Latency Replication Log: the mechanism for maintaining the
    replication log, which can be deployed on a highly available
    non-volatile memory appliance for minimal impact on application
  • Cloud Store Adapter: software that pre-processes data for backup to a
    specific object store or NFS store
  • Crash-Consistent Data Pipe: high-throughput, multi-channel software
    connection that provides a crash-consistent transfer of data from the
    on-premises data center to the cloud destination, ensuring continuous
    data coherence
  • Cloud Acceleration Tier: an extreme low latency data tier in the cloud
    that enables both zero RPO with data consistency and efficient use of
    cloud resources

Why Is This Architecture Important?

JetStream Software co-founder and CTO Serge Shats described the reason
for the unique design of the JetStream Data Protection software. "We
have the ability to continuously capture data for recovery in real time,
as it's being written to storage, but that's just the start. Beyond
capturing data through the IO Filter, we have to satisfy a considerable
number of objectives."

These objectives include:

  • No degradation of application performance on premises
  • High scalability to support environments with thousands of virtual
  • Low latency replication logging for scalable continuous data
  • Support for multiple, concurrent availability policies, assigned per
    recovery group
  • Replication to the recovery destination most appropriate for each
    policy, from a warm VMware environment for cloud failover to an
    economical object store backup site
  • Crash-consistent connectivity with each recovery destination
  • Multiple recovery options: e.g., point-in-time (CDP) or whole group
    failover (DR)

There are hundreds, sometimes thousands, of VMs across the data center,
and they're constantly writing data. "It's a firehose of data I/O,"
explained Shats. "If the connection to the cloud, relatively speaking,
looks more like a garden hose, you have a problem. So to provide a
highly scalable solution for data replication to the cloud, we employ 1)
a low-latency environment for the replication log on premises; 2) the
multi-channel, high-throughput data pipe to transport data to the cloud;
and 3) a high-performance data acceleration tier in the cloud recovery
