Today's Day Two Cloud delves into cloud security and cloud cost optimization for SaaS and public clouds. Our guest is Jo Peterson. On the security front, we compare and contrast traditional on-prem and cloud security challenges, explore the shared responsibility model of cloud security, and more. For cost optimization we discuss the growing concern about cloud costs, why optimization tools still need humans, tips for tracking multicloud spending, and more.

When shopping for DDR4 memory modules, we typically look at the memory density and memory speed. For example a 32GB DDR4-2666 memory module has 32GB of memory density, and the data rate transfer speed is 2666 mega transfers per second (MT/s).
If we take a closer look at the selection of DDR4 memories, we will then notice that there are several other parameters to choose from. One of them is rank x organization, for example 1Rx8, 2Rx4, 2Rx8 and so on. What are these and does memory module rank and organization have an effect on DDR4 module performance?
In this blog, we will study the concepts of memory rank and organization, and how memory rank and organization affect the memory bandwidth performance by reviewing some benchmarking test results.
Memory rank is a term that is used to describe how many sets of DRAM chips, or devices, exist on a memory module. A set of DDR4 DRAM chips is always 64-bit wide, or 72-bit wide if ECC is supported. Within a memory rank, all chips share the address, command and control signals.
The concept of memory rank is very similar to memory bank. Memory rank is a term used Continue reading
While I was developing Network Automation Concepts webinar and the network automation online course, I wrote numerous blog posts on the Network Infrastructure as Code (NIaC) concepts, challenges, implementation details, tools, and sample solutions.
In March 2023 I collected these blog posts into a dedicated NIaC resources page that also includes links to webinars, sample network automation solutions, and relevant GitHub repositories.

According to OpenLogic’s Open Source Adoption and Expansion in 2022 Report, the adoption of Open Source Software (OSS) across all sizes of organizations is rising with 40% of respondents stating an increase of OSS software over the previous year and 36% reporting a significant increase in OSS software usage. The increase in OSS adoption can be attributed to a number of factors including access to the latest innovations, reduction in costs and frequent product updates. However, leveraging community contribution introduces the potential for malicious code to be attached. For example, a series of 2022 case studies conducted by the Package Analysis project, part of the Open Source Security Foundation (OpenSSF), details a number of malicious packages from widely used repositories such as PyPi and NPM. Therefore, it is essential to determine the vulnerabilities in any container image before its deployment into the environment. Calico Cloud’s Image Assurance capabilities enables Vulnerability Assessment for any image. We often hear this referred to as Image Scanning.
In order to assess the posture of container images the components that make up an image must be broken down. We refer to this inventory as the Software Bill of Materials Continue reading
The National Energy Research Scientific Computing Center at Lawrence Berkeley National Laboratory, one of the key facilities of the US Department of Energy that drives supercomputing innovation and that spends big bucks so at least a few vendors will design and build them, has opened up the bidding on its future NERSC-10 exascale-class supercomputer. …

In a world without neatly defined network perimeters, lateral security—means detecting and mitigating threats from malicious actors who are already inside your network—is the new front in cybersecurity. To detect lateral threats, businesses need comprehensive visibility into what’s happening inside their IT estates, not just around them. They need to see every packet and every process at every endpoint.
At the upcoming RSA conference in San Franciso, we’ll be highlighting how VMware technologies like Project Northstar help organizations conquer lateral security threats. Keep reading for a sneak peek of what to expect from the VMware team at the event, and join us at RSA Conference from April 24-27 2023 at Moscone Center, North Expo Booth#5644 in San Francisco to check out the latest innovations in cloud networking and security for yourself.
VMware security strategy consists of five key pillars, and we’ll be showing off all of them at the RSA Conference:
The new geopolitical reality means that China is part of IT Strategy. The supply chain is changing, joint ventures are limited and more.
