Asigra appliance uses Zadara technology

The new Asigra appliance can’t be bought — only rented.

Asigra has partnered with Zadara Storage to release the Asigra Cloud OpEx Appliance. The device is Zadara’s Virtual Private Storage Appliance (VPSA) pre-installed with Asigra’s backup software. Like Zadara’s storage-as-a-service (STaaS) offerings, the Asigra appliance is sold as a subscription, essentially making it a backup appliance as-a-Service.

Asigra will ship the device to the customer’s data center or colocation. All of the storage, controllers and disks are managed. The end customer doesn’t need to bring any storage expertise to the table. All the data is encrypted such that only the end customer can see it — their managed service provider (MSP) can’t.

Asigra sells its products exclusively through channel partners, many of which are MSPs that provide backup-as-a-service (BaaS) and disaster recovery-as-a-service (DRaaS) to end customers. The revenue model of MSPs is subscription-based, but traditionally, procuring storage is based on projected consumption. This means MSPs could end up buying more storage than they need.

Eran Farajun, executive vice president of Asigra, said by buying Asigra backup on an appliance on a pay-as-you-go basis, MSPs avoid overprovisioning and will only pay for the storage they use. Many of Asigra’s MSPs were using Asigra’s backup and Zadara’s STaaS separately, and Farajun said they were the ones who first brought up the idea of packaging the two.

“We’re really just responding to what our market has been asking for,” Farajun said.

Asigra only makes backup software, and all of its converged backup appliances come from partnerships with hardware vendors. The company started in 1986, but didn’t release its first device with pre-installed backup software until 2015 through a partnership with SuperMicro. Asigra began packaging software on iXsystems appliances in 2018. 

render of Asigra Cloud OpEx appliance
The Asigra Cloud OpEx Appliance is based on Zadara’s Virtual Private Storage Appliance.

Marc Staimer, president and founder of Dragon Slayer Consulting, said MSPs operate in a world where capital expenditure (capex) is going against an operational expenditure (opex) revenue stream. Money is made when the streams cross, but MSPs would rather have their costs and revenue be in alignment.

Many of the costs of running a service provider business fall under capex. Staimer said service providers who use the public cloud to provide BaaS and DRaaS need to purchase storage in a high-cost, high-performance tier to ensure fast recovery as well as a low-cost, high-capacity tier to keep overall costs down. According to Staimer, the performance tier costs six times more than the capacity tier.

MSPs also must provision hardware for their end customers. Staimer said MSPs are typically expected to provide the hardware at no cost, as it’s a necessary component of their services.

The Asigra appliance solves both of these problems because it’s entirely pay-as-you-go, with no upfront investment.

“People want a pure opex model,” Staimer said. “It’s a very good move on Asigra’s part.”

The Asigra Cloud OpEx Appliance is generally available now and starts at 30 terabytes of capacity and can scale up to petabytes. Pricing starts at pennies per gigabyte per month.

The Cloud OpEx Appliance uses Asigra’s flagship Asigra Cloud Backup Evolved software. Farajun said he expects updates to the core backup software in early 2020, including security enhancements and better integration with VMware.

Farajun said the next update will also focus on integrating with Microsoft Office 365’s Teams and Groups applications, as well as other cloud-based SaaS applications. He noted he has been seeing more customers realizing the need to protect their SaaS data.

Kubernetes authentication project wrestles with migration problems

Kubernetes has not only matured, it’s showing a wrinkle or two.

In case there was any doubt that Kubernetes is no longer a fledgling project, it has begun to show its age with the accumulation of technical debt, as upstream developers struggle to smooth the migration process for a core set of security improvements.

Kubernetes authentication and role-based access control (RBAC) have improved significantly since the project reached version 1.0 four years ago. But one aspect of Kubernetes authentication management remains stuck in the pre-1.0 era: the management of access tokens that secure connections between Kubernetes pods and the Kubernetes API server.

Workload Identity for Google Kubernetes Engine (GKE), released last month, illuminated this issue. Workload Identity is now Google’s recommended approach to Kubernetes authentication between containerized GKE application services and GCP utilities because Workload Identity users no longer have to manage Kubernetes secrets or Google Cloud IAM service account keys themselves. Workload Identity also manages secrets rotation, and can set fine-grained secrets expiration and intended audience policies that ensure good Kubernetes security hygiene.

GKE users are champing at the bit to use Workload Identity because it could eliminate the need to manage this aspect of Kubernetes authentication with a third-party tool such as HashiCorp’s Vault, or worse, with error-prone manual techniques.

“Without this, you end up having to manage a bunch of secrets and access [controls] yourself, which creates lots of opportunities for human error, which has actually bitten us in the past,” said Josh Koenig, head of product at Pantheon Platform, a web operations platform in San Francisco that hosts more than 200,000 Drupal and WordPress sites.

Koenig recalled an incident where a misconfigured development cluster could have exposed an SSL certificate. Pantheon’s IT team caught the mistake, and tore down and reprovisioned the cluster. Pantheon also uses Vault in its production clusters to guard against such errors for more critical workloads but didn’t want that tool’s management overhead to slow down provisioning in the development environment.

“It’s a really easy mistake to make, even with the best of intentions, and the best answer to that is just not having to manage security as part of your codebase,” Koenig said. “There are ways to do that that are really expensive and heavy to implement, and then there’s Google doing it for you [with Workload Identity].”

Kubernetes authentication within clusters lags Workload Identity

Workload Identity uses updated Kubernetes authentication tokens, available in beta since Kubernetes 1.12, to more effectively and efficiently authenticate Kubernetes-based services as they interact with other Google Cloud Platform (GCP) services. Such communications are much more likely than communications within Kubernetes clusters to be targeted by attackers, and there are other ways to shore up security for intracluster communications, including using OpenID Connect tokens based on OAuth 2.0.

However, the SIG-Auth group within the Kubernetes upstream community is working to bring Kubernetes authentication tokens that pass between Kubernetes Pods up to speed with the Workload Identity standard, with automatic secrets rotation, expiration and limited-audience policies. This update would affect all Kubernetes environments, including those that run in GKE, and could allow cloud service providers to assume even more of the Kubernetes authentication management burden on behalf of users.

We think [API Server authentication tokens] improves the default security posture of Kubernetes open source.
Mike DaneseSoftware engineer, Google; chair, Kubernetes SIG-Auth

“Our legacy tokens were only meant for use against the Kubernetes API Server, and using those tokens against something like Vault or Google poses some potential escalations or security risks,” said Mike Danese, a Google software engineer and the chair of Kubernetes SIG-Auth. “We’ll push on [API Server authentication tokens] a little bit because we think it improves the default security posture of Kubernetes open source.”

There’s a big problem, however. A utility to migrate older Kubernetes authentication tokens used with the Kubernetes API server to the new system, dubbed Bound Service Account Token Volumes and available in alpha since Kubernetes 1.13, has hit a show-stopping snag. Early users have encountered a compatibility issue when they try to migrate to the new tokens, which require a new kind of storage volume for authentication data that can be difficult to configure.

Without the new tokens, Kubernetes authentication between pods and the API Server could theoretically face the same risk of human error or mismanagement as GKE services before Workload Identity was introduced, IT experts said.

“The issues that are discussed as the abilities of Workload Identity — to reduce blast radius, require the refresh of tokens, enforce a short time to live and bind them to a single pod — would be the potential impact for current Kubernetes users” if the tokens aren’t upgraded eventually, said Chris Riley, DevOps delivery director at CPrime Inc., an Agile software development consulting firm in Foster City, Calif.

Kubernetes authentication upgrade beta delayed

After Kubernetes 1.13 was rolled out in December 2018, reports indicated that a beta release for Bound Service Account Token Volumes would arrive by Kubernetes 1.15, which was released in June 2019, or Kubernetes 1.16, due in September 2019.

However, the feature did not reach beta in 1.15, and is not expected to reach beta in 1.16, Danese said. It’s also still unknown how the eventual migration to new Kubernetes authentication tokens for the API Server will affect GKE users.

“We could soften our stance on some of the improvements to break legacy clients in fewer ways — for example, we’ve taken a hard stance on file permissions, which disrupted some legacy clients, binding specifically to the Kubernetes API server,” Danese said. “We have some subtle interaction with other security features like Pod Security Policy that we could potentially pave over by making changes or allowances in Pod Security Policies that would allow old Pod Security Policies to use the new tokens instead of the legacy tokens.”

Widespread community attention to this issue seems limited, Riley said, and it could be some time before it’s fully addressed.

However, he added, it’s an example of the reasons Kubernetes users among his consulting clients increasingly turn to cloud service providers to manage their complex container orchestration environment.

“The value of services like Workload Identity is the additional integration these providers are doing into other cloud services, simplifying the adoption and increasing overall reliability of Kubernetes,” Riley said. “I expect them to do the hard work and support migration or simple adoption of future technologies.”

For Sale – Dell XPS 15″ i7, 32gb, gtx1050, 512gb, 6 cell

Relisted as I now have a replacement machine.
Fantastic condition 9560 and only selling as I have ‘collapsed’ all my stuff to a new dual booting MacBook Pro. I may yet regret that but I’m going to work in Thailand so want to travel as light as possible. One tiny scratch on the lid that i have had to light and zoom in to see (see pics)
18 months old and works perfectly. i7 7700, 32Gb DDR 2400 (upgraded from stock 16gb 2133) and 512gb SSD. Geforce GTX 1050 and Killer Wifi, Bluetooth etc.
Full HD infinity display (matte) and comes boxed with extra official PSU (might have a case too).

For full transparency I noticed a little play in the hinge a few days ago but turns out the screw was a little loose, tightened it up and its all good now. However, I ordered a full replacement set should I ever need to open it again as they are notoriously easy to grind off the head (torx bit), all unused but these will be included.

Please check out all my previous sales as I sell only top quality, well looked after stuff and I am completely clear about everything being well described.

Its very fast and eats through office, Solidworks (can be realhacked for realview graphics), Photoshop etc. all at the same time. I have never gamed on it bit presume it would be fine for that.
Im still not convinced the new MBP will be faster but I cant take all this stuff with me so its a reluctant sale.
Any questions fire away.
