amazon web services - EC2 Instance : Access RDS via Alias Name -

-

is possible set rds in such way ec2 instances use rds instance identifier "mydb" connect rds instead of using public dns name : mydb.cfnr64hlvtcp.us-east-1.rds.amazonaws.com. ?

the way access rds database using public dns endpoint name generated rds when database created.

you setup own cname rds dns name if wanted hide public dns name component in system, must maintain entry, seems bit complicated.

aws recommends don't use ip address behind rds dns entry directly since ip may change, example if database has failover new instance. [1]

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
