Migration Strategies and Vendor Considerations

As always, the correct choice and decision on whether to go with SaaS depend on a broad spectrum of scenarios ranging from – my company being fully self-hosted and wanting to stay that way to having an everything must-be as-a-service goal and everything in between. The following factors and positions may have an influence – for better or worse – on your next step. It’s worth pausing to make sure it’s the right one to avoid pain, frustration, and, of course, being assigned blame for a bad choice:

Your location is remote and not suitable for a SaaS implementation. Your mind is made up if you’re in this cohort, so you probably haven’t read this far.

There are security mandates, meaning SaaS is out of the question. For example, air-gapped is your default setup.

My [blank] Admin makes these decisions, and I leave it to him/her. If this is your position, beware of personal biases or self-serving agendas, and involve multiple stakeholders (including senior decision-makers) in the process to get an outcome that supports the greater good.

I’m an Admin and would love [self-hosted or SaaS Observability], but I don’t have the decision power or budget. It’s definitely worth getting management involved in the next step, whichever that may be. This will likely make IT’s life (and management) much easier going forward.

My vendor said SaaS is the right choice for me, and it’s how the market is going. This may be partially true for you, but beware of the hammer-and-nail syndrome. In other words, if the vendor only offers SaaS, everyone looks like a SaaS customer, even though it may not be the correct choice for some.

My vendor recommends going with their software, as it works best with their gear. Beware of vendor lock-in, as many customers prefer a more decoupled vendor-agnostic approach to future-proof themselves.

I’m greenfield/brownfield etc. Greenfield customers may be more likely to go with SaaS as it will be a much easier position to take.

This is how we’ve been doing it, and I’ll stick to it to be safe. How open (or closed) you are to new and different ways of doing things.

I’m confused and not sure what the next best step is. Do you have a trusted partner you can engage with? Can you take a phased approach as opposed to rip-and-replace?

We could have a much longer list here, but you get the idea. When you plan out your next step, it may mean staying the same, adopting a completely new approach, or a blended position. Most customers will want to proceed cautiously and have an evolutionary, not revolutionary, approach. So it’s worth considering whether you go with or stay with the vendor you go with. We can support you on this journey and straddle the hybrid landscape. Planning migration involves a phased approach. Gradual adoption and systematic data transition mitigate risks, ensuring a seamless shift. Mitigating risks necessitates a robust plan. Adequate backup systems, contingency measures, and comprehensive testing ensure a smooth transition, minimizing operational disruptions.

It’s a good idea to draw up a Vendor Evaluation Checklist. Creating a checklist for evaluating SaaS vendors may include factors such as data security protocols, support responsiveness, and contract flexibility. A thorough evaluation will ensure compatibility with your company’s standards, making sure you tick all the boxes so-to-speak.

Developing criteria for selecting a reliable self-hosted solution demand criteria, including maintenance requirements, scalability potential, and adaptability to evolving tech landscapes. It’s not necessarily an either-or, but it’s about choosing a vendor with both options. Other questions worth pondering are: How good is the SaaS vendor at monitoring the on-premises gear, and similarly, how good is the self-hosted solution at monitoring Cloud gear? Other important dimensions of the ecosystem surrounding the solution under consideration are the level and quality of the training, the quality and responsiveness of support, and the engagement and collaboration of the community (if there is one). This can be the difference between a good product and a good experience.

And finally, don’t forget, as we said at the outset, Observability goes beyond monitoring but is built on a monitoring foundation, and so understanding the track record of the vendor at this level is also important.

Best Practices

Regardless of the chosen solution, adhering to best practices ensures an optimal Observability setup. This should include regular system audits, continuous training, and staying abreast of technological advancements. Your staff and company may not need to use every feature in the solution for the sake of doing so, but they should at least stay abreast of what the solution can do that is of value to your company. This will help form the foundation for success.

Tips for optimizing performance, security, and cost-effectiveness include regular performance audits, implementing robust security measures, and periodic cost-benefit analyses to ensure ongoing efficiency.

Conclusion

The Observability Dilemma requires organizations to consider their needs, costs, and security carefully. They must embrace a strategic decision-making process, evaluating SaaS and self-hosting options based on customization, scalability, and operational ease. It’s crucial to view Observability as more than just monitoring, ensuring it proactively safeguards system health. A strategic decision-making matrix guides organizations through considerations, balancing customization with security and scalability.
