Por que uma análise de custo-benefício é essencial para uma implementação bem-sucedida de nuvem privada?

A cost-benefit analysis is crucial for successful private cloud implementation as it ensures financial viability and strategic alignment. Incorporating FinOps, it evaluates the economic impact, balancing initial costs against long-term benefits, ensuring cost transparency. DevOps integration assesses operational efficiency gains, like improved deployment speed and automation. AIOps contributes by predicting resource needs and optimizing performance, leading to cost savings. This analysis fosters informed decision-making, aligning IT investments with business goals and ensuring the private cloud delivers value in terms of cost, performance, business value, and scalability.

Not every migration to the cloud is going to save you money-if you don't use tools for e.g. AWS Pricing Calculator. What sets that service apart is its transparent analysis without selling you the service. Spinning up the analysis from there, gives you a good deal of knowledge and prompts to ascertain your exposure and estimates. Benefit or not is another story hinging on your firm's priorities, short/long term business goals, investment plans, and a plethora of things. So it's best to narrow it down to what you want to achieve and let for e.g. this tool do the rest for you and show you what it's going to cost so you see for yourself it's going to benefit or not. Mapping your DC & apps vs the view of the services of cloud will surprise you!

In the word ‘Cost Benefit Analysis’, often cost takes all the lime light and focus as it is more tangible and easy to arrive at. Seldom there is focus on benefits beyond cost. The indirect benefits in terms of improvement in overhead reduction, security posture, automation and agility needs to be highlighted as key goals than just focusing on cost. To emphasise the importance of the non-tangible benefits, focus on IMPACT. For ex, what could be the impact on product releases in terms of timelines and effort. Taking a sample project really helps to demonstrate to the leadership the IMPACT. A business case with a strong CBA can help make quick decisions. At the same time, a bad one can stall progress.

Imperative for Alternatives to be an option. Nature of business, drivers to move/not move, clear org vision are factors in making the decision based on CBA and the view you have with you. Is the cloud provider reliable enough to secure and protect my data and apps is the first question that should pop up - generating revenue/profitability comes later. You can't earn from what you can't protect. Are my client's trusting me enough for me to recommend they move their workloads to the cloud - how good a job am I doing in convincing them on the benefits thereof? Using the tools stated above, have I been thorough to give them at least three alternatives based on their use cases, etc? Am I being cognizant and their advocate for them to understand?

While you decide to migrate, you must be aware of the parallel costs I am going to incur. Taper off those and ramp up on the cloud costs, in parallel. The trick is in minimizing the overlap. For that being thorough should be in order. Not only future costs, but even the cost of keeping your DC and infra there, the sale of the same may offset the cost a bit. Then the journey on the cloud - with all the optimizations that you saw in the CBA, you need to track those minutely. Tools such as AWS Cost Explorer, Budgets, give you an excellent way to keep a tab. Even to the minutest of details like changing your type of EC2 instance (VM), changing your storage method, database, backup frequency, and I could go on...That requires focus and skill.

With the tools mentioned above, you are now able to draw up a list of all the services you are using and you have carefully looked at each item/service you are using to ensure it not only meets your needs but is also advising you to optimize continually - case in point AWS Trusted Advisor for example. You see that you could go serverless on some applications instead of incurring extra costs by running them traditionally. Cool benefits. Stop idle EC2 instances, their EBS volumes, look for cost efficient S3 Storage options instead of default. Tag your services and review them in the dashboard. Use spot instances instead of dedicated ones.

Like all things, cloud migration and working natively in the cloud is a journey. Big-bang savings from the moment you "go-live" may be a misnomer. The trick is being vigilant and a good steward of the business by tracking each service closely, having the checks and balances in the org/system to ensure costs are tracked minutely and someone is tracking the benefits too and at some point, they merge to show you the real picture. Your ROI has to come up tall. Real tall. That will show thoroughness and razor-sharp focus. We do live in a fiercely competitive world, right? You don't use a lot of your existing hardware as you rely on the cloud provider so there itself you have some benefits.
