“…In [7], the authors state that virtualization can hide some failures at the software level and that failures at the operating system level can affect both active and standby VMs if running in a lock-step way. Beyond that, virtualization introduces additional software layers imposing additional delays to network datagrams [29]. Consequently, performance measurements can also be affected by virtualization; authors in [29] show that clockrelated measurements are affected by CPU load in the host as well as in the network load.…”

High availability in clouds: systematic review and research challenges

Cloud Computing has been used by different types of clients because it has many advantages, including the minimization of infrastructure resources costs, and its elasticity property, which allows services to be scaled up or down according to the current demand. From the Cloud provider point-of-view, there are many challenges to be overcome in order to deliver Cloud services that meet all requirements defined in Service Level Agreements (SLAs). High availability has been one of the biggest challenges for providers, and many services can be used to improve the availability of a service, such as checkpointing, load balancing, and redundancy. Beyond services, we can also find infrastructure and middleware solutions. This systematic review has as its main goal to present and discuss high available (HA) solutions for Cloud Computing, and to introduce some research challenges in this area. We hope this work can be used as a starting point to understanding and coping with HA problems in Cloud.

The popularization of the Linux kernel at data center servers became a significant factor to consider when developing or deploying network applications. New “packet processing frameworks” emerged to ensure fast packet processing inside these servers that rely on the Linux kernel, XDP and DPDK being the two main ones. Alongside this, Cloud Computing environments dominated the data center scenario, bringing virtualization to the center of these servers. This research compares DPDK and XDP packet processors when subject to a cloud computing environment with I/O, CPU, and network load. We first describe an architecture that implements frameworks and emulates a cloud environment. We measure throughput and packet loss while varying the number of competing VMs, CPU usage by the frameworks, and packet size and present our results in the form of takeaways. Furthermore, we conclude that the virtual environment can impact the performance of both frameworks depending on the received packet size and the type of workload the cloud environment performs. A significant case to highlight is when the cloud environment performs network load, and the servers receive small-sized packets, creating both throughput degradation and increasing packet loss. We conclude our experiments by conducting statistical non-parametric hypothesis tests to enhance our conclusions and have a closer look at the results.

“…KVM requires a virtualization hardware extension processor like Intel VT or AMD-V. KVM has also been transported in the form of loadable kernel modules to other operating systems such as FreeBSD and illumos. In addition, KVM offers para-virtualization support to visitors using the VirtIO API for Linux, OpenBSD, FreeBSD, NetBSD, Plan 9, and Windows [20]. It includes a paravirtual Ethernet chip, disk I/O controller, balloon module, and SPICE or VMware driver VGA graphics adapter.…”

Virtualization is now the most efficient and successful procedure to use server resources. Virtualization is a technology that will efficiently allow the instructions or programs based on the available hardware. With the help of virtualization, we can achieve benefits like reduced capital and operating costs, minimized downtime, increased productivity, and good disaster recovery, etc. This work compares the virtual mail server performance on 3 different Hypervisor software. The 3 different type-2 hypervisor software we chose to compare were Kernel-based Virtual Machine (KVM), Oracle VirtualBox, and VMware. A computer system that sends and also receives an email over a network either on LAN or the internet is called a Mail Server. Although large ISPs and public email services have their dedicated hardware, in most cases, the web servers and mail servers are hosted on a single machine by virtualization. When a Mail server is implemented on the hypervisor, it is then considered as a virtual mail server. A virtual mail server is good at load balancing and has many more benefits. This paper presents how to implement a virtual mail server and shows the comparative results of the virtual mail server on different type-2 hypervisor software. HIGHLIGHTS Virtualization will efficiently run the instructions or programs based on the available hardware The virtual mail server has more significant advantages than the standard mail server. It helps in achieving faster deployment of mail servers with fewer hardware requirements Comparison of the performance of the virtual mail server on three different Type-2 Hypervisor software: Kernel-based Virtual Machine (KVM), Oracle VirtualBox, and VMware The web servers and mail servers can be hosted on a single machine by virtualization A virtual mail server is best for load balancing and disaster recovery as well
