Thinking about deploying your app in the cloud? Don’t get lost among the variety of options. Here you can find some of the most popular solutions in order to find a perfect match for your business.
Do you remember the times cloud computing boosted a new era of IT services and development? Cloud technologies capitalized on open-source distributed teams and remote testing.
Just remember the launch of GitHub and the idea to review the code and build software alongside other developers.
Though cloud computing is no longer a buzzword, private vs. public cloud debate is still relevant.
Public cloud is based on shared physical hardware owned by a cloud services provider.
With this option, you pay only for the computing resources you use. The benefits also include high deployment speed and flexible scaling options based on your business demand. The public cloud is good for SMEs with dynamic business growth and a limited budget. The main drawback is higher security risks for your data and less control over availability of your applications.
Private cloud offers similar flexibility and scalability although the most important data are stored within private and strongly protected resources. The cloud is hosted on-site or in a service provider’s data center. Computer and storage components are customized for your business requirements. The private cloud is a perfect match for big companies with rigid data obligations and predictable business demand.
Most developers use two main deployment options for an app code.
Infrastructure as a Service (IaaS). On this platform, a provider hosts a virtual or physical machine and ensures connectedness and initial provisioning of the system. The installation of software, application run times, and databases is up to you. IaaS requires that you have strong skills in system administration to apply firewall rules, patches, etc. on a frequent basis. You’re totally responsible for the system’s uptime and security as well. The most popular vendors on the market are Google Cloud Platform, Microsoft Azure, and Amazon Web Services.
Platform as a Service (PaaS). This category of cloud services runs on top of IaaS. The cloud provider maintains the application server or other middleware, databases, and system components. So, feel free to concentrate on the app code. You may be restricted to certain versions of packages available so the vendor could manage the system in the right way.
An example is AWS Relational Database Service (RDS).
Vendor lock-in casts a shadow on cloud-computing benefits. A situation in which a customer using a service cannot easily switch to a competitor’s platform is profitable to the cloud providers. Many companies stay with a vendor that doesn’t meet their requirements just to avoid the complex process of migration.
Why so? To move data from one provider’s cloud to another one may require moving the cloud data to the new provider’s environment. As most businesses strive for small or zero downtime as well as a secure transition, the migration might be really challenging and complex.
Having assisted our clients in migration, from Heroku to Amazon cloud for example, we reached the conclusion that the best way to avoid the vendor lock-in is to make sure your choice of cloud vendor does not put a drag on your growth strategy. Think very carefully not only about what your business needs are now, but also how they are likely to evolve in the years to come. At K&C, we help with those decisions, and we’re ready to take on your migration headaches, should you have any.
