AWS GovCloud Goes East

AWS GovCloud Goes East

Among several exciting announcements we heard at AWS re:Invent 2018 was one that hit close to our Loudoun County home – the new AWS GovCloud (US-East) Region. Joining GovCloud (US-West), the first of its kind, the East region is the second for AWS GovCloud and the 19th AWS region in the world. This announcement is significant, particularly to the Washington DC area of the east coast, home to the ParkMyCloud headquarters and a significant number of U.S. government departments and agencies.

The US-East region adds three more Availability Zones to AWS GovCloud, doubling the three total that were previously included with the existing infrastructure. This is great news for U.S. customers in the public and commercial sector in highly regulated industries that must meet stringent compliance requirements, including those for disaster recovery and continuity of operations. The new region is compatible with EC2, S3, and RDS instance types, among more.

Why does AWS GovCloud matter?

The advantages of scalability, security, and agility in the cloud are alluring. But for customers with sensitive data and strict compliance and security requirements, like government agencies, using the cloud is a tricky process with a huge checklist to follow. To provide the same benefits of cloud services while meeting even the most stringent U.S. government requirements, Amazon designed an isolated cloud region only for those users – AWS GovCloud.

What’s Different in AWS GovCloud?

Think of AWS GovCloud as Amazon’s “gated community.” GovCloud vets all of its government customers and their partners to create secure cloud solutions, meeting compliance requirements for FedRAMP, the DOJ’s Criminal Justice Information Systems (CJIS), U.S. International Traffic in Arms Regulations (ITAR), Export Administration Regulations (EAR), Department of Defense (DoD) Cloud Computing Security Requirements Guide (SRG), FIPS 140-2, IRS-1075, and more. This specialized region allows for customers to host sensitive Controlled Unclassified Information (CUI) that includes data in categories such as agriculture, patent, export, critical infrastructure, immigration, law enforcement, proprietary business info, statistical, tax, financial, and transportation, to name a few. GovCloud is ideal for government agencies at the federal, state, and local level, as well as organizations in regulated industries including financial, technology, energy, healthcare, law enforcement, defense, enterprise, and aerospace.

How do I qualify to be a GovCloud customer?

GovCloud is only available to vetted U.S. entities and root account holders with U.S. citizenship. AWS ensures address compliance in the cloud with network, data, and virtual machines that are isolated from all other AWS cloud regions. GovCloud features a separate identity and access management stack with unique credentials that work only within the AWS GovCloud region. In addition, the region is managed solely by AWS personnel of U.S. citizenship, on U.S. soil, and users get their own separate management console. The region also has endpoints specific to its region, including the option to use designated endpoints, meeting FIPS 100-2 compliance requirements.

Why go GovCloud?

Whether it’s Personally Identifiable Information (PII), patient medical records, financial data, law enforcement data, or other forms of CUI, AWS GovCloud allows users to meet compliance requirements on their cloud journey. Government agencies have an opportunity with Amazon to support mission critical workloads for enterprise applications, high performance computing, big data, storage & disaster recovery. For a U.S. cloud with vetted access, that meets compliance, guards data, improves identity management, protects workloads, and enhances cloud visibility, AWS GovCloud is the way to go.

Resisting Amazon – Why Retailers Choose AWS Alternatives

Resisting Amazon – Why Retailers Choose AWS Alternatives

Although Amazon dominates the market share of cloud services, there’s been a trend among retailers to choose AWS alternatives. Big-name retailers, in verticals from clothing to electronics, are moving away from maintaining their own data centers in favor of the public cloud’s agility and better access to customers worldwide. To highlight a few:


Gap Inc. signed a five-year contract with Microsoft, choosing Azure as their primary cloud provider. Employees will also be using Microsoft 365 tools and the Enterprise Mobility and Security suite. They chose Azure to support their e-commerce operations, inventory, and workforce systems.

Gap chose Azure among AWS alternatives because they wanted “a partner that is not going to be a competitor […] in any other parts of their businesses,” as told by Shelley Bransten, corporate VP for global retail and consumer goods at Microsoft.


Walmart teamed up with Microsoft on a five-year contract back in July. The partnership, promising to “further accelerate digital innovation in retail,” was a natural fit since Microsoft was already partnered with Walmart, handling significant workloads, apps, and teaming up their engineers.

Furthermore, in a move directly targeting Amazon, Walmart has asked their tech vendors to choose AWS alternatives. Wal-Mart spokesman Dan Toporek told CNBC: “Our vendors have the choice of using any cloud provider that meets their needs and their customers’ needs. It shouldn’t be a big surprise that there are cases in which we’d prefer our most sensitive data isn’t sitting on a competitor’s platform.”


Supermarket and retail giant Kroger took a multi-cloud approach, first with Pivotal and Microsoft, and later adding on Google Cloud in 2017. In a CNBC interview, Chris Hjelm, Kroger’s chief information officer, explains why the retailer spends millions of dollars on Microsoft and Google in order to avoid AWS: “For obvious reasons competitively, it doesn’t make sense for us to do a ton to help grow that business for them.”


Target, another retail competitor of Amazon, decided to stop financing its rival in mid-2017 and began dropping down their use of AWS. Microsoft, Google, and Oracle all pushed for their business as discussions were kept quiet, with a Target spokesperson only admitting that they use multiple clouds. Earlier this year, Google CEO Sundar Pichai confirmed Target as a big cloud customer.  

And the list goes on…

In addition to the rest, Spotify, eBay, Best Buy, and LL.Bean all turned to Google to meet their cloud needs. One by one, big retailers with recognized names are choosing Microsoft and Google in favor of Amazon.

Why Retailers Choose AWS Alternatives

Cloud migration requires a massive haul of data, costs, and time from a business. Not only is there a lot to consider in terms of pricing, services, and overall offerings, but there are also certain needs unique to a specific industry. Big retailers turning away from AWS and onto other cloud providers highlights an issue for Amazon as a competitor in the retail industry, providing opportunities for other providers like Microsoft and Google to secure enterprise deals.

Meanwhile, not everyone has chosen AWS alternatives. Amazon still holds the market lead and continues to retain a footprint in the retail industry with customers including Nordstrom, Nike, Under Armour, and Lululemon. So while sources suggest that more retailers are looking for other options outside of AWS, time will tell if Amazon can hold its spot among retailers.

Alibaba ECS Instance Types Comparison
