Driving a modern applications strategy: Four ways to accelerate modern applications initiatives
Many organizations have begun embracing cloud-native techniques to develop new apps, using microservices that can be independently scaled and quickly updated.
But what about existing business-critical applications that can’t be abandoned? A modern applications approach can provide a bridge — enabling services implemented in monolithic architectures to collaborate alongside these new cloud-native services.
This eBook describes the benefits of adopting this modern applications approach, along with four techniques for accelerating the shift.
Benefits of modern applications
Faster response and innovation
Updating monolithic applications requires rebuilding the entire package — even for a minor change. Because cloud-native applications are comprised of a series of modular services that communicate via APIs, developers can quickly add innovative new features and update existing capabilities independently.
Greater scalability and change tolerance
Because the micro-services underlying cloud-native applications are loosely coupled, they can be stopped and started and scaled up and down independently. This makes them more reliable and resilient to changes in the service levels of the infrastructure where they are running. It also means they can be scaled out across a multiple clouds if needed.
Reduced risk and improved productivity
Automation is an integral part of the modern applications approach. Tools that enforce policy and reduce manual steps create repeatable processes that eliminate opportunities for errors and reduce effort required for implementing and operating underlying infrastructure.
Four techniques to accelerate modern applications success
- Don’t try to re-invent the wheel
- Optimize Day 2 Operations
- Tech estate: Leverage Existing Investments
- Minimize disruption and lock-in
In the next section, we will dive deeper on each of these recommendations and how to put it into practice.
Don’t try to re-invent the wheel
Building your own modern application stack almost never creates differentiated value
The modern application ecosystem is comprised of many open-source tools. Kubernetes — the leading container orchestration software is curated by The Cloud Native Computing Foundation. A modern applications platform requires many other capabilities including image registry, persistence, networking, monitoring, security and more. Selecting and integrating those components to assemble a production-ready platform requires hard-to-find skills and very rarely adds any unique value. Furthermore a custom cloud-native platform usually results in a snowflake configuration that is difficult to sustain and scale to production.
Turnkey solutions for modern app infrastructure
Focus on the strategic outcomes that modern applications drive by selecting a turnkey, production-ready platform. Avoid sourcing and configuring individual components. Streamline the procurement and configuration of your modern apps platform. Leveraging a standardized architecture that is pre-configured speeds time to production and ensures the ability to reliably go from development to production at scale.Deploy in as few as14 days
Day 2 Operations
Risk of downtime and data loss
With so many components in a modern application stack, lifecycle management can become overwhelming quickly. Feature enhancements and security patches require regular updates to the platform. Failure to apply patches and updates comes with the risk of downtime and security incidents. Developers and operators can end up spending their time maintaining the integrity of the stack instead of deploying features that differentiate the business. Modern applications are being used for more business-critical systems. That drives the need for the right business continuity and disaster solution to avoid the risk of data loss.
Maintain and scale the right service levels
By adopting a platform that automates patching, and updating to new releases, organizations can ensure the stability and security of their modern applications architecture while keeping developers focused on innovation. This capability allows verified updates to be downloaded automatically, which takes the underlying infrastructure from one known good state to the next non-disruptively. It removes the barriers to keeping the platform current so that new features and security enhancements can be accessed as soon as they are available. This, in turn, frees up staff to focus on tasks that add value to the operation. The right business continuity and disaster recovery solution will include the ability to protect both virtual machines and containers.92%
Tech Estate: Leverage existing investments
Incompatible environments cause disruption and raise costs
Few organizations can afford to start from scratch and walk away from existing investments in infrastructure and staff. For your modern applications approach to be successful, traditional and cloud-native approaches must co-exist pragmatically. While proprietary cloud-native stacks excel at delivering new functionality in containerized microservices, they are incompatible with valuable legacy applications that run the business. If existing infrastructure and current skills are not extended into your modern applications practice, DevOps process flows will be inherently disjointed and your architecture unsustainable.
Add cloud-native capabilities incrementally now to your existing operation
The pragmatic approach is to enhance infrastructure and staff that are currently supporting virtualized apps and Infrastructure-as-a-Service in a way that adds support for containers and Kubernetes orchestration. Modern applications will combine services from both traditional monolithic apps and emerging containerized apps, and it makes sense to have those applications on the same infrastructure. Cloud-native skills are at a premium, staff with knowledge of legacy systems are valuable in their own right. You can ensure that you maximize the value you derive from both by equipping staff with tools that allow them to support cloud-native capabilities with their existing skill set.82%
Architect for consistency
Multi-cloud deployments suffer from inconsistent infrastructure and operations
Most organizations plan to support multiple cloud deployment options including private cloud and public clouds. When applications aren’t compatible across clouds, IT can’t simply place workloads on the clouds best aligned to their needs. Governance and compliance across clouds is complicated because of variations in operational procedures, management interfaces, security policies and monitoring tools.
Streamline operations with hybrid cloud consistency
Business, technical, operational and financial considerations should drive where an application is run — not compatibility limitations. The right approach allows the same VM or container to be moved unchanged, providing frictionless workload placement agility — we call this consistent infrastructure. A consistent operational framework improves governance, security, compliance and DevOps productivity. This hybrid cloud consistency should extend across all environments, from on-premises to edge and public cloud. This limits operational silos, increasing efficiency and reducing risk.4,200
