Proxy Reverso para múltiplos sites do ArcGIS server.

Question

<\/HEAD>Estamos planejando atualizar nosso proxy reverso do Windows Server 2008 r2 e estamos pesquisando qual a melhor forma de configurar o servidor substituto (ainda usando IIS).<\/P> <\/P> A questão interessante é que temos múltiplos sites do ArcGIS server (https:\/\/oururl.com\/arcgis1, https:\/\/oururl.com\/arcgis2,<\/A> etc...). Cada site é gerenciado por um único servidor. No proxy reverso atual, estamos usando ARR e URL Rewrites para encaminhar o tráfego de entrada para os servidores corretos.<\/P><\/P> As informações da Knowledge Base (veja os links abaixo) nas quais baseamos este design parecem indicar que isso se aplica às versões 10 até 10.4 e estamos apenas verificando se isso ainda é considerado uma boa prática ou se há novas recomendações. A documentação atual não entra em tantos detalhes. A maior dúvida específica é se o ARR é necessário, embora eu não tenha certeza de como redirecionaríamos o tráfego corretamente sem ele.<\/P> <\/P> Suspeito que devemos usar a mesma arquitetura e que o silêncio da Esri após a versão 10.4 seja mais porque eles não querem fornecer suporte específico para IIS.<\/P> <\/P> Qualquer opinião, comentário ou crítica severa será bem-vinda.<\/P> <\/P> Obrigado.<\/P> <\/P> Artigos legados da KB das versões 10-10.4:<\/P> Como Fazer: Configurar um proxy reverso com ArcGIS 10.1 para Server no IIS ARR<\/A><\/P> Como Fazer: Configurar um proxy reverso com ArcGIS 10.1 para Server no IIS ARR com SSL<\/A> <\/P><\/P> Informações atuais sobre proxy reverso (sem informações sobre ARR/IIS):<\/P> Configurar um servidor proxy reverso com ArcGIS Server014Deploy | ArcGIS Enterprise<\/A> <\/P><\/BODY><\/HTML>

hi,

You just need the loadbalancer.If your application in .net then i will help with that.

Please let me know

Thanks for the response, Travis.

I don't think there's any functionality that we would lose, we would just need to properly reconfigure how some things work. I think (I wasn't here at the time) ARR was used with the intent to load balance using IIS server farms but in reality all of our farms are single machines so that's not really being utilized. These farms include both ArcGIS Server sites & general web applications.

We are currently using web adaptors for each of our AGS sites, they're running on the AGS server machines instead of the reverse proxy. Not sure what we gain/lose if we move the web adaptors to the reverse proxy other than maybe reduce the number of URL Rewrite rules we have to create.

We don't have a corporate load balancer and the reverse proxy server we're using is dedicated solely for our GIS needs.

We don't have a compelling reason to change the architecture but we're reviewing the architecture as part of replacing the reverse proxy & application servers. Our AGS servers are on updated OS so they're not part of this update process.

Thanks again for the feedback, I understand why Esri wouldn't want to go down the rabbit hole of providing IIS support.

Hello,

You can certainly setup ArcGIS Server with a third party reverse proxy or with Esri web adaptors which is just a reverse proxy + load balancer (which I would say is the most common approach for the majority of our customers). My main question would start with: Do you feel you would lose any functionality by using web adaptors instead of your current method? Certainly if you have a corporate reverse proxy or load balancer you can feel free to use that instead of a web adaptor. That being said, Esri Support may be limited in terms of troubleshooting and supporting IIS and its URL rewrite module as our software just isn't in the picture in that scenario (as opposed to when there is a web adaptor) and that is why our documentation will be limited on that subject as well.

If you are in an unfederated (no Portal) environment, you certainly have the ability to "test run" the web adaptor in this new setup. You can configure 1, 5, 10, etc. web adaptors if you would like and see if it works for you. If not, you can always use your current approach.

Travis
