…Microsoft Azure platform allows customers to seamlessly extend their infrastructure into the cloud and build multi-tier architectures. Additionally, third parties can enable enhanced capabilities by offering security services and virtual appliances. This white paper provides an overview of security and architectural issues that customers should consider … It also covers creating more secure services in Azure virtual networks…

Example 1: Build a perimeter network (also known as DMZ, demilitarized zone, or screened subnet) to help protect applications with network security groups (NSGs).
Example 2: Build a perimeter network to help protect applications with a firewall and NSGs.
Example 3: Build a perimeter network to help protect networks with a firewall, user-defined route (UDR), and NSG.
Example 4: Add a hybrid connection with a site-to-site, virtual appliance virtual private network (VPN).
Example 5: Add a hybrid connection with a site-to-site, Azure VPN gateway.
Example 6: Add a hybrid connection with ExpressRoute.

#HotTopic #AzureUpdate – VNET Peering | Public #ChristmasEarly

July 28, 2016 Comments off

“…VNet Peering provides the ability to link two Virtual Networks in the same geo region directly. It allows Virtual Machine resources in both the VNets to connect directly through private IP addresses as if it were part of the same network. VNet peering achieves this by routing packets between the Virtual Networks through the internal Azure backbone network and thus does not involve any gateway in the path. This allows for a low latency, high bandwidth connection between the Virtual Machines in the VNets. VNet peering also allows transit through the peered VNets, thus a Network Virtual Appliance or a VPN gateway in one VNet can be used by a Virtual Machine in another peered VNet. Peering will work across VNets in different subscriptions and between an ARM (V2) and ASM (V1) VNet. It does not work between two ASM VNets….”  http://bit.ly/2awjIRe

#Azure 101 Blob Storage…To Block or Page that is the question #Blob #Object #AzureStorage

July 15, 2016 Comments off

..Block blobs are optimized for streaming and storing cloud objects, and are a good choice for storing documents, media files, backups etc…..

Page blobs are optimized for representing IaaS disks and supporting random writes, and may be up to 1 TB in size. An Azure virtual machine network attached IaaS disk is a VHD stored as a page blob

Blob Storage stores unstructured object data. A blob can be any type of text or binary data, such as a document, media file, or application installer. Blob storage is also referred to as Object storage.
