Composants du VMware SD-WAN<\/strong><\/h4>\n\n\n\n

Le VMware SD-WAN Edge, SD-WAN Gateway et SD-WAN Orchestrator<\/a> se combinent pour fournir les diff\u00e9rentes fonctionnalit\u00e9s de l'offre VMware.<\/p>\n\n\n\n

Le SD-WAN Bord<\/a> est un CPE bas\u00e9 sur x86 qui ex\u00e9cute r\u00e9seau virtuel<\/a> (VNF). Sa fonction est de connecter un bureau ou un site aux applications en nuage, aux ressources informatiques et aux services virtualis\u00e9s. Il se connecte au syst\u00e8me de VMware SD-WAN<\/a> Passerelles.<\/p>\n\n\n\n

Les passerelles sont d\u00e9ploy\u00e9es dans les centres de donn\u00e9es afin d'optimiser les voies de circulation pour garantir les performances et fournir des services d'assistance \u00e0 la client\u00e8le. s\u00e9curit\u00e9<\/a> services comme les pare-feu<\/a>.<\/p>\n\n\n\n

Le SD-WAN Orchestrator<\/a> pr\u00e9voit des politiques d'entreprise \u00e0 l'\u00e9chelle du r\u00e9seau qui permettent au r\u00e9seau de s'adapter pour atteindre les objectifs de l'entreprise. En outre, il permet d'ins\u00e9rer des services dans le r\u00e9seau, de surveiller le r\u00e9seau en temps r\u00e9el et d'analyser les performances des applications.<\/p>\n\n\n\n

Caract\u00e9ristiques<\/strong><\/h4>\n\n\n\n

VMware consid\u00e8re la demande de bande passante comme un d\u00e9fi majeur<\/a> pour les entreprises dot\u00e9es de r\u00e9seaux \u00e9tendus traditionnels. Bien qu'un r\u00e9seau \u00e9tendu bas\u00e9 sur MPLS soit fiable, il n'est pas extensible. \u00c9tant donn\u00e9 que les entreprises utilisent des le nuage<\/a> De plus en plus pour les applications critiques, elles ont besoin d'\u00e9volutivit\u00e9 et d'une plus grande bande passante. Une solution SD-WAN comme celle de VMware compl\u00e8te le r\u00e9seau MPLS existant d'une entreprise par une connectivit\u00e9 \u00e0 large bande et LTE. Les connexions alternatives ont l'avantage d'\u00eatre moins ch\u00e8res, plus rapides que MPLS, de fournir plus de bande passante et d'\u00eatre accessibles. <\/p>\n\n\n\n

En m\u00eame temps, les connexions internet publiques ont leurs limites. Avec l'internet public, le temps de disponibilit\u00e9 n'est pas n\u00e9cessairement le m\u00eame et les donn\u00e9es n'arrivent pas \u00e0 destination de mani\u00e8re aussi fiable. Pour y rem\u00e9dier, VMware SD-WAN surveille, mesure et optimise automatiquement les chemins de trafic en temps r\u00e9el. Cela permet de s'assurer que les connexions Internet publiques sur lesquelles transitent les donn\u00e9es fonctionnent \u00e0 des niveaux suffisants. De plus, en cas de mauvaise connexion, les donn\u00e9es peuvent \u00eatre transf\u00e9r\u00e9es vers une connexion plus op\u00e9rationnelle, m\u00eame si l'autre connexion provient d'un autre FAI<\/a>. <\/p>\n\n\n\n

Les VPN peuvent \u00eatre automatiquement \u00e9tablis lorsque les politiques de s\u00e9curit\u00e9 sont d\u00e9clench\u00e9es. Les politiques sont d\u00e9finies par le logiciel orchestrateur du r\u00e9seau, qui est contr\u00f4l\u00e9 par les administrateurs du r\u00e9seau dans un lieu central. Cela permet de s\u00e9curiser les connexions entre tous les sites de l'entreprise, les centres de donn\u00e9es ou les sites d'h\u00e9bergement. le nuage<\/a>.<\/p>\n\n\n\n

VMware SD-WAN pour les succursales<\/strong> <\/h3>\n\n\n\n

Les r\u00e9seaux \u00e9tendus traditionnels et certains SD-WAN n'\u00e9tendent pas la virtualisation aux succursales. Ces sites d\u00e9centralis\u00e9s se retrouvent alors avec des bo\u00eetiers \u00e0 fonction fixe inefficaces. Le d\u00e9ploiement et la maintenance de ces bo\u00eetiers sont \u00e0 la fois complexes et co\u00fbteux. Le VMware SD-WAN relie les succursales au reste du r\u00e9seau gr\u00e2ce \u00e0 son dispositif SD-WAN Edge. L'un de ces dispositifs, qui ex\u00e9cute plusieurs VNF, peut remplacer un groupe de bo\u00eetiers \u00e0 fonction fixe. De plus, comme le dispositif SD-WAN Edge a virtualis\u00e9 l'\u00e9quipement de la succursale, la visibilit\u00e9 du r\u00e9seau s'\u00e9tend \u00e0 l'activit\u00e9 du r\u00e9seau local de la succursale.<\/p>\n\n\n\n

Gr\u00e2ce aux capacit\u00e9s d'orchestration de l'offre VMware, m\u00eame si la succursale est un bureau ou un travailleur \u00e0 distance, les employ\u00e9s peuvent se connecter au reste du r\u00e9seau \u00e9tendu et \u00e0 la destination finale des donn\u00e9es d'une application. avanc\u00e9e<\/a> Les politiques, la qualit\u00e9 de service et le contr\u00f4le d'acc\u00e8s aux applications peuvent \u00eatre orchestr\u00e9s quel que soit l'endroit o\u00f9 se trouve le travailleur ou l'application. L'orchestrateur peut \u00e9galement g\u00e9rer n'importe quel appareil ou r\u00e9seau utilis\u00e9 par l'employ\u00e9.<\/p>\n[\/et_pb_text][\/et_pb_column]\n\t\t\t[\/et_pb_row]\n\t\t[\/et_pb_section]","protected":false},"excerpt":{"rendered":"

The VMware SD-WAN<\/a> by VeloCloud product features include high performance, high reliability, virtualisation of appliances, cloud integration, automation, and easy orchestration. VMware also emphasizes that the product is effective at virtualising the infrastructure of an enterprise\u2019s branch locations.<\/p>\n\n\n\n

Redvine currently runs and operates Gateways across South Africa and multiple locations across Africa, this is under the official license from Velocloud. <\/p>\n\n\n\n

Components of the VMware SD-WAN<\/strong><\/h4>\n\n\n\n

The VMware SD-WAN Edge, SD-WAN Gateway, and SD-WAN Orchestrator<\/a> combine to provide the various features of the VMware offering.<\/p>\n\n\n\n

The SD-WAN Edge<\/a> is an x86-based CPE that runs virtual network<\/a> services (VNFs). Its function is to connect an office or location to cloud applications, compute resources, and virtualized services. It connects to the system of VMware SD-WAN<\/a> Gateways.<\/p>\n\n\n\n

The Gateways are deployed at data centers to optimize traffic paths for assured performance and provide security<\/a> services like firewalls<\/a>.<\/p>\n\n\n\n

The SD-WAN Orchestrator<\/a> provisions business policies network-wide that make the network adapt to meet business goals. In addition, it allows for services to be inserted into the network, monitors the network in real-time, and analyzes application performance.<\/p>\n\n\n\n

Features<\/strong><\/h4>\n\n\n\n

VMware sees bandwidth demand as a major challenge<\/a> for enterprises with traditional WANs. While an MPLS-based WAN is reliable, it is not scalable. Since enterprises are using the cloud<\/a> more and more for mission-critical applications, they need scalability and more bandwidth. An SD-WAN solution like VMware\u2019s adds to an enterprise\u2019s existing MPLS with broadband and LTE connectivity. The alternative connections have the benefits of being cheaper, faster than MPLS, providing more bandwidth, and being accessible. <\/p>\n\n\n\n

At the same time, public internet connections have their limitations. With the public internet, there is not necessarily the same amount of uptime and data doesn\u2019t get to its destination as reliably. To combat this, the VMware SD-WAN automatically monitors, measures, and optimizes traffic paths in real-time. This ensures the public internet connections that data travels on are operating at sufficient levels. Also, in the case of a bad connection, data can be transferred to a more operable connection, even if the other connection is from a different ISP<\/a>. <\/p>\n\n\n\n

VPNs can automatically be established when security policies are triggered. The policies are defined by the orchestrator software of the network, which is controlled by network administrators in a central location. This secures connections between any enterprise locations, data centers, or the cloud<\/a>.<\/p>\n\n\n\n

VMware SD-WAN for Branch Offices<\/strong> <\/h3>\n\n\n\n

Traditional WANs and certain SD-WANs do not extend virtualization into the branch. These decentralized locations then are left with inefficient fixed-function boxes. Deployment and maintenance of such boxes are both complex and expensive. The VMware SD-WAN connects branch locations to the rest of the network with its SD-WAN Edge device. One of those devices running multiple VNFs can replace a group of fixed-function boxes. Plus, since the SD-WAN Edge device virtualized the branch equipment, network visibility extends to network activity in the branch LAN.<\/p>\n\n\n\n

The VMware offering\u2019s orchestration abilities mean even if the branch is a remote office or a remote worker, employees can connect to the rest of the WAN and the end destination of an application\u2019s data. Security<\/a> policies, quality of service, and application access control can be orchestrated no matter where the worker, or application, is. The orchestrator can also handle any device or network the employee may use.<\/p>\n","_et_gb_content_width":"1080","om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-3033","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-articles"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/posts\/3033","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/comments?post=3033"}],"version-history":[{"count":5,"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/posts\/3033\/revisions"}],"predecessor-version":[{"id":100872,"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/posts\/3033\/revisions\/100872"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/media\/2868"}],"wp:attachment":[{"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/media?parent=3033"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/categories?post=3033"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/redvine.io\/fr\/wp-json\/wp\/v2\/tags?post=3033"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
