SaaS Comes at You Fast

These days, it seems only a software-defined application delivery platform can keep up with the needs of multi-cloud and dynamic infrastructure.

Insight into the right steps to take for migrating workloads to public cloud and successfully reducing cost as a result. Read the Guide.

It’s an exciting time to be software! Chances are you were brought into the world through continuous delivery, making a loving team of DevOps parents very proud… and very, very happy. Your potential is unlimited! The only thing that could possibly prevent you from growing up to fulfill your SaaS destiny is a poor application delivery strategy.

Your Grandfather Was a Monolithic App

In a simpler time, maybe five or six years ago, applications were monolithic in nature, making delivery a straight forward process. That’s no longer the case, as today’s modern apps are distributed and often powered by microservices like containers or cloud services. DevOps teams these days need to make sure every component of the application is performing as expected. But that’s just the start, as they also must make sure the connective tissue of these distributed apps isn't underperforming, which could create a terrible end-user experience. Software-defined application delivery allows you to decide exactly how you want your application to be experienced by the end user, and easily write contingency-based code to implement those rules. Changes to your application architecture aren’t a major concern since your rules can accommodate both planned and unexpected changes.

Your Generation Is Right at Home on Heterogeneous Infrastructure

Like applications, modern infrastructure has also changed significantly in the last several years. No longer are you using a single data center, or perhaps a data center and one CDN to make sure your app gets to your customers. Multi-CDN infrastructures allow you to re-route app traffic when performance is an issue. Multi-cloud environments are becoming more and more prevalent as enterprises want to avoid public cloud vendor lock-in and gain more control over their critical shared infrastructure. And of course, the data center you purchased a few years ago isn’t just gathering dust…you paid for it, so you’re using it. The net result is a heterogeneous set of infrastructures being used to deliver you to customers.

Kids Today With Their Dynamic Infrastructure

Even if your infrastructure is fully built out and provisioned, it is, by the nature of the cloud, constantly changing as instances are both spun-up and de-provisioned. Often, and for many reasons, this happens without you explicitly knowing about it. Software-defined application delivery helps you optimize your infrastructure in its current state, again using the business rules you decide on. This has the additional benefit of giving you a better idea of how to plan for cloud capacity and avoid overpaying since you can automate delivery based on your reserved instances and fully utilize the capacity you paid for. Your Software-defined application delivery also accounts for changes in cloud provider pricing and specific geographic needs, keeping the end of month bill surprises to a minimum.

Moving Sucks

There aren’t any shortcuts when it comes to migrating applications to the cloud. The first step in cloud migration needs to be making sure your application can be delivered to your worldwide customers before, during, and after the migration. Do you really want to do that manually, while in the middle of a migration? Software-defined application delivery systems make sure your app reaches customers at all times.

Learn to Speak a Multi-Cloud Foreign Language

There are plenty of reasons to shift to a multi-cloud infrastructure plan: avoiding cloud lock-in, protection against massive cloud outages, leveraging certain vendor-specific services or offerings, and good old fashion Cloud SLA negotiation leverage. But once you’ve made the decision to add a second cloud vendor to your infrastructure, it’s time to start thinking about how to ensure your app delivery is optimized for multi-cloud environments. Having your Ops team do so manually with each vendor isn’t likely to be a popular strategy. The only way to manage delivery is with a software-defined abstraction layer on top of both clouds. Your Software-defined application delivery speaks both cloud “languages”, and does all the translating for you, automatically.

Your Grandfather’s Application Delivery Controllers Can’t Keep Up

Remember the monolithic app? Its best friend was the Application Delivery Controller (ADC), also built for a different age. Often built into a blinking hardware box in a data center, old guard ADCs had several drawbacks. They required a significant upfront expense, as opposed today’s cloud pay as you go model. Monitoring was done with synthetic testing only, not the combination of real-user and synthetic monitoring many software-defined application delivery solutions provide today. Most importantly, ADC solutions were not as easily configurable and customizable as the robust software-defined application delivery, making them unusable with today’s modern application architecture.

Get in a Routine

As more and more concerns (security, DevOps, new technologies, etc.)  are added to the Ops team’s list of things to worry about, the need for process automation becomes paramount. Software-defined application delivery automation has the very practical effect of removing many common delivery issues, such as micro-outages, service degradations, and the occasional (and highly newsworthy) public cloud outage from the “worry” list.  Your uptime and customer experience should all be ensured by a set of routing rules you determine ahead of time. You can’t put a price on peace of mind, or not getting a million “OUR APP IS DOWN!!!!!” emails.

Outages and cloud service degradation happens, so you need a plan in place for when they do. Many companies choose to utilize multiple cloud providers to ensure their application is always available to worldwide customers, even during an outage. Taking control over changes in public cloud service offerings, pricing models, and SLAs is another powerful motivator for Ops teams to move to a multi-cloud architecture. Software-defined application delivery allows you to seamlessly and automatically deliver applications over multiple clouds and/or CDNs, factoring in real-time availability, costs structures, and application performance.

There's No Fate But What We Make for Ourselves

There’s no way you can keep up with constantly changing applications, the infrastructure they’re built on, and inevitable network issues with manual processes. Software-defined application delivery allows you to implement the business rules that you know are important to the app delivery process, and do so instantly and automatically via customizable code. End user experience, network latency, unplanned cloud provisioning or CDN bursting, and other considerations can all be factored in as your needs change. The multiple application delivery fail-safe layers will keep you insulated from the outages that need to be mitigated during your Game of Thrones viewing.
