RISC vs. CISC

Reading Time: 4 minutesNot all the different CPUs are the same: they may have a different Instruction Set Architecture (ISA). An Instruction Set Architecture (ISA) is part of the abstract model of a computer that defines how the CPU is controlled by the software. The ISA acts as an interface between the hardware and the software, specifying both what the processor is capable of doing as well as how it gets done. The ISA provides the only way through which a user is able to interact with the hardware. It can be viewed as a programmer’s manual because […]

AWS Graviton processor for ARM based EC2 instances

28 November 2018
Comments off

Reading Time: 3 minutesDuring the last AWS re:Invent 2018, Amazon Web Services (AWS) has announced new EC2 Instances (A1) Powered by ARM-based AWS Graviton Processors, which promise cost savings up to 45 percent for certain workloads. Built around ARM cores and making extensive use of custom-built silicon, the A1 instances are optimized for performance and cost. They are a great fit for scale-out workloads where you can share the load across a group of smaller instances. This includes containerized microservices, web servers, development environments, and caching fleets.

VMware ESXi on Raspberry Pi

Reading Time: 5 minutesDuring the VMworld US 2018, one of the announces was the VMware ESXi for ARM porting, specific for the embedded and edge IoT systems, so not like a general purpose solution for all ARM servers (but an interesting move to increase the possibility for bringing the virtualization on ARM). VMware demonstrated ESXi on 64-bit ARM running on ARM hardware built to common industry standards; note that VMware demonstrates not just virtualization, but also resilient operations and ease of management at the Edge, via FT-protected 64-bit Arm VMs and vMotion in a high-availability DRS cluster…

VMware ESXi for ARM: make sense?

31 August 2018

Reading Time: 4 minutesFour years ago I’ve written a post about the Virtualization with ARM based servers when some vendors announce the possibility to have new server’s series based on the ARM processor. Now seems that there are more than rumors with the announce, during the latest VMworld US 2018, of VMware vSphere for ARM. To be honest, not exactly vSphere, but just ESXi… anyway an interesting announce. But to be clear, limited to embedded and edge IoT systems, so not like a general purpose solution for ARM servers.

Virtualization with ARM based servers?

9 January 2014

Reading Time: 2 minutesDuring the past months I’ve seen some posts and tweets enthusiastic on the a possible introduction of new server’s series based on ARM processor, with some considerations on how they could change the actual scenarios, for example in the virtual infrastructures. But I have really some doubts in the server scenarios or at least in the virtualization user case: first to all we have to notice that most of the hypervisor are designed for the Intel/AMD server. Actually VMware vSphere (but also Microsoft Hyper-V) is working only with Intel/AMD x64 platform in order to provide […]
