Services Instalasi, Konfigurasi, dan Training Virtualisasi Proxmox VE


Apa itu Proxmox VE ?

Proxmox VE (Virtual Environment) merupakan distro khusus untuk virtualisasi yang dibangun dari basis distro Debian minimal dan berjalan dalam modus teks. Meski berbasis teks, proses manajemen Proxmox Virtual Environment mudah dilakukan melalui akses web, termasuk melakukan instalasi sistem dengan menggunakan teknologi VNC.

Proxmox merupakan salah satu teknologi alternatif selain VMware dan Xen, sangat cocok untuk development ataupun production. Bagi para Sysadmin yang ingin melakukan development atau membangun lab sendiri namun terkendala dalam hal lisensi, proxmox merupakan salah satu alternatif. Selain free, fitur yang ditawarkan juga tidak kalah dari teknologi virtualisasi lain.

Beberapa produk teknologi virtualisasi antara lain VMware vSphere, Oracle VM, Citrix Xen Server, Redhat RHEV, dan lain-lain.

Layanan yang kami berikan sebagai berikut :

Menambah new category – Virtualization dan VMware


Berangkat dari dorongan teman agar postingan di blog ini juga menambahkan kategori baru, yaitu virtualisasi maka per hari ini gw tambahkan topik baru yaitu virtualization, vmware, kvm, xen, dan cloud technology.

Semoga penambahan kategori baru ini memberikan dorongan semangat bagi saya untuk lebih banyak menulis tentang cloud dan virtualisasi dan memberikan pengetahuan dan pengalaman baru bagi saya dan teman-teman pengunjung blog ini.

Nantikan tulisan-tulisan saya selanjutnya !

Oracle VM : Enterprise class virtualization software from Oracle


Adopsi teknologi virtualisasi XEN oleh Oracle telah mencapai tahap yang lebih advanced. Oracle VM 3.0. Dalam klaimnya, Oracle mengatakan bahwa mereka dapat men-deliver kemampuan virtualisasi lebih baik daripada VMware dengan harga lisensi yang lebih murah. Bahkan sebenarnya Oracle VM 3.0 adalah gratis dan lisensi dapat dibeli secara subscription. Artinya support baru didapatkan jika membeli lisensi. Jika tidak, maka Oracle VM 3.0 dapat digunakan secara gratis tanpa support.

Berikut perbandingan antara Oracle VM dan VMware :

Reason Oracle VMware Resources
1. Application-Aware
  • Oracle offers a complete applications-to-disk stack, and virtualization is fully integrated across all layers
  • Oracle’s virtualization solutions are aware of what’s running inside the virtual machine and can provision and manage applications, middleware, and databases
  • VMware’s virtualization/ hypervisor has no awareness of the database, middleware, and applications running inside it
2. Lower Cost
  • Unlike VMware, Oracle VM is free to download, use, and distribute
  • Affordable support fees
  • Simple licensing
  • High cost of ownership
  • Very high license, support, and management costs
  • Complex licensing
3. Integrated Management
  • Full stack management
  • Manages the hypervisor, physical server, and the applications running in it
  • Multiple vendor tools needed for managing the hypervisor and what’s running inside it
4. Accelerating Application Deployment
  • Oracle VM Templates offer pre-installed, pre-configured virtual machines of enterprise software including CRM, ERP, clustering, and management, enabling you to deploy in minutes and hours as opposed to days and weeks
  • Oracle Virtual Assembly Builder makes it easier to package multi-tier applications and then deploy them with the click of a button
  • Best practices for accelerating deployment of complete virtual infrastructure via Oracle VM Reference Configurations
  • Virtual appliances are via a community marketplace, not vendor supported
5. High Availability
  • Oracle offers high availability for the entire stack—not just the hypervisor level
  • Oracle views clustering and virtualization as complementary technologies
  • Oracle VM customers can achieve additional high availability from using Oracle Clusterware and Oracle Real Application Clusters (Oracle RAC)
  • High availability is only at the hypervisor level; VMware is completely unaware of application crashes
6. Architected for Efficiency
  • Architected for low overhead when moving from physical to virtual servers
  • Aggressive testing with real Oracle Database and application workloads
  • Oracle has a single engineering team for Linux and Oracle VM, leading to better optimization between Xen and Linux
  • Architecture is prone to inefficiency
7. Integrated Support
  • One call to Oracle; no finger pointing at another vendor
  • Full stack is certified and supported
  • Faster time to resolution
  • Need to deal with numerous vendors for the complete stack and management
See what customers are saying about the value of integrated support:

8. Virtualization Built into the System
  • In addition to Oracle VM, Oracle offers virtualization built into its hardware and the Oracle Solaris operating system
  • Oracle Solaris Containers and Oracle VM for SPARC allows multiple applications to be run on a single system
  • Dynamic Domains are included in SPARC Enterprise M-Series servers, enabling greater hardware utilization and providing a high level of isolation from other domains
  • Only offers x86 virtualization
9. Comprehensive Platform Support
  • Oracle VM is available for both x86 and SPARC architectures
  • Only x86 platform is supported

Sepertinya sangat luar biasa cara Oracle memasarkan produk nya.

Virtualization on Redhat Enterprise Linux (RHEL)


Baru ngeh setelah dapet link informasi tentang virtualisasi yang disupport oleh RHEL. Ternyata mulai dari RHEL 5, Redhat sudah mulai memakai teknologi virtualisasi KVM dan bukan lagi XEN.

Berikut perbandingan fiturnya :

Virtualization Limits for Red Hat Enterprise Linux (RHEL) Hypervisors

a) RHEL5 KVM and Xen Virtualization
b) RHEL6 KVM Virtualization
c) Red Hat Enterprise Virtualization (RHEV-H)

Red Hat Enterprise Linux Technology capabilities and limits (supported[/theoretical])[1]

The RHEL Virtualization support matrix can be found here.

Notes:

[1] Supported limits reflect the current state of system testing by Red Hat and its partners for mainstream hardware. Systems exceeding these supported limits may be included in the Hardware Catalog after joint testing between Red Hat and its partners. If they exceed the supported limits posted here, entries in the Hardware Catalog will include a reference to the details of the system specific limits, and are fully supported. In addition to supported limits reflecting hardware capability, there may be additional limits under the Red Hat Enterprise Linux subscription terms. Supported limits are subject to change as on-going testing completes.

[2] Supports a maximum of 125 CPUs across entire machine.

[3] Requires Intel EPT or AMD RVI technology support.
