I sat down this weekend and had a look at my finances as I'm almost 5 months into my 2nd year as a full-time solo consultant, and noticed that my revenue streams have changed quite a bit over the last 3 years.
This is the result of a conscious effort to reduce my reliance on a few large clients, and also to offset seasonalities and other factors that can affect revenue and create a healthy mix of active and passive income streams.
Overall revenue has grown over time, and my largest client now accounts for less than 20% of my revenue. And I haven't seen too much seasonality to my work yet - summer was quieter because Europeans went on holiday, but it was still OK.
I have learnt a lot from @jonathanstark about value pricing and I'm well on the way of moving away from hourly pricing for most of my engagements. I think developing passive income also helps with that, as it softens the blow when I had to say no to potential clients.
I briefly toyed with the idea of forming an agency with my closest friends but quickly realised that it'd take me away from doing what I love - teaching, solving problems and building stuff. So, solo consultant it is for the foreseeable future for me!
Honestly, this journey has been pretty wild, I'm still learning so much still on a daily basis, and it's still the best career decision I have made in a long time, and I'm excited by what lies ahead!
In hindsight, I should have explained what those categories meant to me since they often mean the same thing to many people.. oops! 😅

re:Invent starts tomorrow, so let me round up the biggest #serverless related announcements from the last 2 weeks (I know, crazy!) and share a few thoughts on what they mean for you.

Mega 🧵If this gets 168 retweets then I'll add another batch!

#serverless #aws #reinvent
1. Lambda released Logs API which works with the Lambda Extensions mechanism that was released in Oct. This lets you subscribe to Lambda logs in a Lambda extension and ship them elsewhere WITHOUT going through CloudWatch Logs

aws.amazon.com/about-aws/what…
Why is it important?

a. it lets you side-step CloudWatch Logs, which often costs more (sometimes 10x more) than Lambda invocations in production apps.
b. it's possible (although not really feasible right now) to ship logs in real-time

X: in light of last week's #AWS outage, should I make my app multi-region?
me: it depends.
X: on what?
me: how much did the outage cost you in lost sales, reputation cost, etc.? And how much are you willing to invest in improving your uptime in case of another region-wide outage?
X: erm... I'm not sure...
me: don't get me wrong, if you're a large enterprise, I expect you to be multi-region already! Hell, I expect you to be doing chaos engineering and proactively finding weaknesses in your architecture before disasters strike and force you into reacting.
me: but as we can see from these AWS outages, modern systems are complex, and even companies who like AWS who have invested heavily into resilience and are doing all the right things, 💩still happens

X: when would you NOT use #AppSync?
me: since AppSync gives you managed #GraphQL server as a service, so if you need a REST API instead then you won't use AppSync. Also, you wouldn't use AppSync if you need GraphQL/Apollo features that are not supported by AppSync
X: what sorta features are you talking about?
me: you can't define custom scalar types (e.g. LatLon is a popular one), and implementation-specific features like Apollo federations for schema stitching, or utilities like data loaders github.com/graphql/datalo…
X: ok, do you need them to build a product app?
me: no, you can absolutely build production apps without them, but these features can be very useful in some contexts, for example, Netflix uses federation heavily netflixtechblog.com/how-netflix-sc…

X: what's your opinion on VTL templates vs direct lambda invocations with AppSync?
me: you should use VTL templates (e.g. for DynamoDB) by default until it's either impossible or the VTL is getting too complex
X: but why?
me: well, let's see..
me: you can do whatever you want with Lambda, that gives you a lot of flexibility, but also all the drawbacks
X: such as?
me: cold starts, esp for resolvers that don't see a lot of traffic or the complexity overhead for mitigating them (Provisioned Concurrency or lambda warmer)
me: and you also have to consider the operational limits specific to Lambda, such as the *soft regional concurrency limit, and the *hard limit of 500 new concurrent executions per min after the init burst capacity (3000 concurrent executions)
X: ok, fair point.. anything else?

Editing my conversation with @lajacobsson for @RealWorldSls and there's a nugget of insight that I wanted to share with you about implicit coupling that we often overlook when using SNS with SQS.

#serverless #aws

1/
The topic is usually owned by the publisher and deployed in the publisher's stack, and the subscriber would reference its ARN via a CloudFormation stack output or something, creating an implicit coupling there.

2/
You need message attributes to do filtering, but the publisher has no idea what the subscriber cares about (nor should it, loose coupling and all). So teams that own the subscriber have to ask the publisher's team to add the message attributes they need.

Minor update - the website is up, and I'd love to hear your feedback on the curriculum.

Are there anything in particular that you'd like to learn? Am I missing anything glaringly obvious?
