Protecting What Matters: Why the AWS Cloud is Designed for Resilience

The public cloud has been with us for some time now, the market is maturing, and adoption has never been more streamlined. The move to the cloud is gathering pace, with research suggesting that 83% of enterprise workloads will be in the cloud by 2020.

However, the debate about the relative merits of private infrastructure over the cloud when it comes to resilience continues to play out.

Many organisations still harbour concerns that the cloud cannot offer them the same level of reliability or protection as on-premise infrastructure in the event of a disaster. But following major investment in innovative functionality by cloud providers such as Amazon Web Services (AWS), now could be the ideal time to re-consider.

Multiple availability zones

Perhaps one of the strongest arguments for the reliability of the public cloud lies in the extent of the vendors’ global reach.

AWS, for instance, builds its global infrastructure around regions and availability zones which makes for a more highly available, fault tolerant, and scalable service than you could achieve with traditional single or multi data centre infrastructures.

The AWS Cloud spans 60 Availability Zones within 20 geographic regions around the world.

This opens up a whole host of benefits, because a cloud solution with multiple availability zones can deliver improved performance, fewer interruptions and more availability by enabling customers to deploy applications across multiple zones.

An added advantage is that organisations can choose to replicate their data between geographic regions for an additional layer of business continuity. And companies can retain complete control over the region in which their data is physically located to meet regional compliance and data residency requirements.

Data replication

Continuous availability is becoming increasingly important to businesses operating in a competitive 24/7 economy.

Failover recovery environments which switch operations to standby servers and systems in the event of a failure used to be enough to keep a business up and running. But today’s critical workloads demand a much more robust approach.

Data replication offered by cloud vendors such as AWS can transform disaster recovery by delivering a faster, more efficient way to store and extract enterprise data.

AWS helps businesses to manage their data replication by extracting data from the source database and loading it into the destination database with zero downtime. Extracting the data can be done quickly and efficiently within minimal effort.

The AWS Database Migration Service handles many of the complex details associated with migration, including data type transformation and conversion from one database platform to another, for example, from Oracle to Amazon Aurora.

Another key benefit of data replication comes with the scalability of cloud-based services. This means organisations don’t need to spend time, money and resources updating their databases, and there are no compromises on the quality of your data storage. Businesses stand to gain additional cost benefits with this approach too.

Direct connections to your network

Consistent network performance is the cornerstone of an organisation’s resilience, but network latency over the internet can vary, affecting the way that data travels from A to B.

AWS Direct Connect is a cloud service solution that can address this issue by making it easy to establish a dedicated network connection from your premises to AWS. Using AWS Direct Connect, you can establish private connectivity between AWS and your data centre, office or working environment.

With AWS Direct Connect, you choose which data uses the dedicated connection as well as the way that data is routed, giving you a more consistent network experience than Internet-based connections can provide.

And in many cases, this direct connection to your network can reduce your network costs and increase bandwidth throughput.

With the advent of these enhanced cloud features, it certainly seems that any lingering concerns about the reliability of the public cloud can be put aside for good.

Protection, reliability and availability are now fundamental elements of the cloud service, and one thing is certainly clear – AWS cloud has been designed for resilience.
