AWS Announces the General Availability of Amazon EBS io2 Block Express Volumes – InfoQ.com

Published

 on


Amazon Elastic Block Store (EBS) volumes are a key Elastic Compute (EC2) component with several HDD and SSD volumes, each designed for a particular use case. And recently, AWS announced the general availability of its cloud-based storage area network (SAN) offering, Amazon EBS io2 Block Express volumes – providing 4x higher throughput, IOPS, and capacity than io2 volumes.

Last year at re:Invent 2020, the company previewed Amazon EBS io2 Block Express volumes as a SAN offering. It is designed according to AWS to meet the requirements of the largest, most I/O-intensive, mission-critical deployments of Microsoft SQL Server, Oracle, SAP HANA, and SAS Analytics on AWS. The volumes are now generally available first with Amazon EC2 R5b instances powered by the AWS Nitro System, which delivers the highest EBS-optimized performance. Support for other instances besides R5b is coming soon. In addition, with the GA release, the io2 Block Express volumes now also support io2 features such as Multi-Attach and Elastic Volumes.

Channy Yun, a principal developer advocate for AWS, explains in an AWS News blog post on the GA release:

The new Block Express architecture delivers the highest levels of performance with sub-millisecond latency by communicating with an AWS Nitro System-based instance using the Scalable Reliable Datagrams (SRD) protocol, which is implemented in the Nitro Card dedicated for EBS I/O function on the host hardware of the instance. Block Express also offers modular software and hardware building blocks that can be assembled in many ways, giving you the flexibility to design and deliver improved performance and new features at a faster rate.

Users can create io2 Block Express volumes in the Amazon EC2 console, AWS Command Line Interface (AWS CLI), or an SDK with the Amazon EC2 API when creating R5b instances. Next, after selecting the EC2 R5b instance type, on the Add Storage page, under Volume Type, users can choose Provisioned IOPS SSD (io2) – and the new volumes will be created in the Block Express format.

Amazon EBS io2 Block Express volumes can be an alternative to enterprises for their on-premise solution. In an AWS press release on the GA release, the company states:

io2 Block Express volumes reinvent block storage and give customers the performance they expect from a SAN, but with the elasticity of AWS, unlimited scale, and flexibility of pay-as-you-go pricing—at as low as half the cost of a typical SAN. io2 Block Express volumes are designed for applications that benefit from high-volume IOPS, high throughput, high durability, high storage capacity, and low latency.

tweet by Igor Nemy, technologist at labSpaceSys, says:

Public clouds are getting closer and closer to be identified as large mainframes. SAN volume with 256k IOps, 4GB/s throughput, and 99.999% of durability. I won’t be surprised if this is powered by bespoke ARM-based Nitro (!side-) project.

Currently, io2 Block Express volumes are available in all regions where R5b is available – which include US East (Ohio), US East (N. Virginia), US West (Oregon), Asia Pacific (Singapore), Asia Pacific (Tokyo), and Europe (Frankfurt). In addition, the company announced that support for more regions is coming soon. 

Note that AWS bills the io2- and io2 Express volumes the same way and recommends using tags to identify costs associated with io2 Block Express volumes. Pricing details of io2 volumes are available on the Amazon EBS pricing page.

Security researcher reveal Zoom flaws that could've allowed attackers to take over your Mac – Yahoo Canada Shine On

Published

 on


Zoom’s automatic update option can help users ensure that they have the latest, safest version of the video conferencing software, which has had multiple privacy and security issues over the years. A Mac security researcher, however, has reported vulnerabilities he found in the tool that attackers could have exploited to gain full control of a victim’s computer at this year’s DefCon. According to Wired, Patrick Wardle presented two vulnerabilities during the conference. He found the first one in the app’s signature check, which certifies the integrity of the update being installed and examines it to make sure that it’s a new version of Zoom. In other words, it’s in charge of blocking attackers from tricking the automatic update installer into downloading an older and more vulnerable version of the app.

Wardle discovered that attackers could bypass the signature check by naming their malware file a certain way. And once they’re in, they could get root access and control the victim’s Mac. The Verge says Wardle disclosed the bug to Zoom back in December 2021, but the fix it rolled out contained another bug. This second vulnerability could have given attackers a way to circumvent the safeguard Zoom set in place to make sure an update delivers the latest version of the app. Wardle reportedly found that it’s possible to trick a tool that facilitates Zoom’s update distribution into accepting an older version of the video conferencing software.

Zoom already fixed that flaw, as well, but Wardle found yet another vulnerability, which he has also presented at the conference. He discovered that there’s a point in time between the auto-installer’s verification of a software package and the actual installation process that allows an attacker to inject malicious code into the update. A downloaded package meant for installation can apparently retain its original read-write permissions allowing any user to modify it. That means even users without root access could swap its contents with malicious code and gain control of the target computer.

The company told The Verge that it’s now working on a patch for the new vulnerability Wardle has disclosed. As Wired notes, though, attackers need to have existing access to a user’s device to be able to exploit these flaws. Even if there’s no immediate danger for most people, Zoom advises users to “keep up to date with the latest version” of the app whenever one comes out.

‘Genshin Impact’ Sumeru Gift Codes For Free Primogems, 3.0 Character Banners, Release Date – Forbes

Published

 on


At long, long last, Genshin Impact just wrapped up its new 3.0 special program, revealing a whole lot of new information about the new region, the new element, Dendro, new characters and of course, there are free goodies if you hung out and wached the stream. Or even if you didn’t, I have them right here.

We’ll just get these out of the way first, here are the three gift codes for free primogems and other materials that you can redeem here. These ones are only good for 24 hours, I believe, so you better hurry.

  • 8ANCKTWYVRD5 – 100 Primogems and 10 Mystic Ore
  • EA7VKTFHU9VR – 100 Primogems and 5 Hero’s Wit
  • KT7DKSFGCRWD – 100 Primogems and 50,000 Mora

Past that, the most pressing information is probably the release date for Genshin Impact’s Sumeru update, which is August 24, 2022.

We also were told about the first two character banners for 3.0, which will include three total Sumeru characters with only one five star. Those are:

  • Phase 1 – Tighnari (5 star), Zhongli (5 star), Collei (4 star)
  • Phase 2 – Ganyu (5 star), Kokomi (5 star), Dori (4 star)

While other Sumeru characters were shown or teased onscreen, it will be deeper into the 3.0 patch series before we get to those, which is not unexpected, given that’s how Inazuma worked, and we ended up getting new Inazuma characters for essentially an entire year. And we’re probably still not done.

Sumeru is probably going to end up being the most significant addition to the game to date, because unlike Inazuma, it’s not just a new region, it also has an entirely new element being added to the game for the first time, Dendro. While Dendro has cropped up here and there among a few enemy types, this is the first time we as players can wield it ourselves, and these new characters will be our first introduction to the concept. Like all the elements, you can probably have attack/defense/support focused teammates using the element, and we’ll have to spend some time digging deep into all the new characters to find out exactly how best to use them in their new roles with this new elemental type supporting your team.

Genshin Impact continues to generate massive amounts of revenue, and I have to imagine the Sumeru region is going to boost that even further, even in the face of new rivals like Tower of Fantasy that has just arrived this month. Genshin is the gold standard at the moment and it’s going to be hard to compete with it as it expands to seven massive regions over the next few years.
