Previously, we discussed in very high level about different threat vectors which enterprises need to be able to address cloud services problems and using Skyhigh to address those problems. The role of IT is changing from provider to enabler and service broker. We want to remove the stigma of Shadow IT which implies people are doing something … Continue reading Skyhigh Cloud Security Part2: Let There be Light

If the security is the number one concern of cloud … Continue reading Skyhigh Cloud Security Part 1: Let there be light
Security Challenge on Azure
There are few common security related questions when we start planning migration to Azure:
- How can we restrict the ingress and egress traffic on Azure ?
- How can we route the traffic on Azure ?
- Can we have Firewall kit, Intrusion Prevention System (IPS), Network Access Control, Application Control and Anti – Malware on Azure DMZ ?
This blog post intention is to answer above questions using following Azure features combined with Security Virtual Appliance available on Azure Marketplace:
- Azure Virtual Network (VNET)
- Azure Network Security Groups (NSGs)
- Azure Network Security Rule
- Azure Forced Tunelling
- Azure Route Table
- Azure IP Forwarding
- Barracuda NG Firewall available on Azure Marketplace

We have discussed Azure ExpressRoute via Equinix Cloud Exchange on my previous blog. Equinix Cloud Exchange (ECX) also provides AWS Direct Connect connectivity which means you can share the same physical link (1GBps or 10GBps) between Azure and AWS! ECX also provides connectivity service to AWS for connection speed less than 1GBps. AWS Direct Connect provides dedicated, private connectivity between your WAN or datacenter and AWS services such as AWS Virtual Private Cloud (VPC) and AWS Elastic Compute Cloud (EC2).
AWS Direct Connect via Equinix Cloud Exchange is Exchange (IXP) provider based allowing us to extend our infrastructure that is:
- Private: The connection is dedicated bypassing the public Internet which means better performance, increases security, consistent throughput and enables hybrid cloud use cases (Even hybrid with Azure when both connectivity using Equinix Cloud Exchange)
- Redundancy: If we configured second AWS Direct Connect connection, traffic will failover to the second link…

Microsoft Azure ExpressRoute provides dedicated, private circuits between your WAN or datacentre and private networks you build in the Microsoft Azure public cloud. There are two types of ExpressRoute connections – Network (NSP) based and Exchange (IXP) based with each allowing us to extend our infrastructure by providing connectivity that is:
- Private: the circuit is isolated using industry-standard VLANs – the traffic never traverses the public Internet when connecting to Azure VNETs and, when using the public peer, even Azure services with public endpoints such as Storage and Azure SQL Database.
- Reliable: Microsoft’s portion of ExpressRoute is covered by an SLA of 99.9%. Equinix Cloud Exchange (ECX) provides an SLA of 99.999% when redundancy is configured using an active – active router configuration.
- High Speed speeds differ between NSP and IXP connections – but go from 10Mbps up to 10Gbps. ECX provides three choices of virtual circuit speeds in Australia: 200Mbps, 500Mbps…
